[106]*106ANNETTE KINGSLAND ZIEGLER, J.
¶ 1. This is a review of an unpublished decision of the court of appeals, State v. Lepsch, No. 2014AP2813-CR, unpublished slip op. (Wis. Ct. App. Nov. 19, 2015) (per curiam), which affirmed the La Crosse County circuit court's1 judgment of conviction of defendant Jeffrey Lepsch ("Lepsch") and order denying Lepsch's motion for postconviction relief.
f 2. A jury found Lepsch guilty of killing two individuals during an armed robbery in La Crosse, Wisconsin.2 Lepsch was sentenced to consecutive life terms in prison. Before this court, Lepsch argues he is entitled to a new trial due to alleged errors pertaining to jury selection and the jury Lepsch received.
¶ 3. More specifically, Lepsch presents the following arguments: (1) Lepsch's right to a trial by an impartial jury was violated because certain of the jurors in his case were subjectively and objectively biased; (2) Lepsch's right to due process of law was violated because of circumstances that created the likelihood or appearance of bias and because of alleged deficiencies in the circuit court's investigation into and mitigation of these circumstances; (3) Lepsch's right to be present at a critical stage of his proceedings, right to a public trial, and right to a jury properly sworn to be impartial were violated because the La Crosse County Clerk of Courts administered the oath to the prospective jurors in Lepsch's case outside of Lepsch's pres[107]*107ence;3 and (4) Lepsch's right to receive the proper number of peremptory strikes, to full use of those strikes, and to have biased jurors removed for cause was violated by the circuit court. Lepsch explains that "all of the issues litigated in this appeal have been raised via a claim of ineffective assistance of counsel."4
¶ 4. We conclude that each of Lepsch's claims fails, and that he is not entitled to a new trial. Consequently, we affirm the decision of the court of appeals.
I. FACTUAL AND PROCEDURAL BACKGROUND
¶ 5. On September 15, 2012, police were dispatched to a store in La Crosse, WI. The bodies of P.P. and A.P had been discovered by a family member at the store; each had been shot in the head. There were also signs of a robbery.
¶ 6. On October 10, 2012, Lepsch was charged with two counts of first-degree intentional homicide, contrary to Wis. Stat. § 940.01(1)(a). The following day, an amended complaint was filed additionally charging Lepsch with armed robbery with use of force, contrary to Wis. Stat. § 943.32(1)(a) and (2), and possession of a firearm by a felon, contrary to Wis. Stat. § 941.29(2)(a). On October 25, 2012, at Lepsch's arraignment, Lepsch [108]*108stood mute and the circuit court entered pleas of not guilty on his behalf. A few months later, the case was set for a jury trial.
¶ 7. Jury selection in this case proceeded as follows. Prior to the date of jury selection, prospective jurors completed paper questionnaires asking dozens of questions on subjects ranging from the jurors' favorite television shows to the jurors' views on various legal propositions. These questionnaires required a signature under the following statement: "I affirm, under penalty of perjury, that I have given complete and honest answers to all of the questions above." The parties agreed to excuse about two dozen prospective jurors at least in part on the basis of the answers provided. On July 23, 2013, jury selection itself occurred. Prospective jurors gathered in the "jury assembly room," where they were sworn by the La Crosse County Clerk of Courts. The parties seem to agree that neither Lepsch nor his attorneys were present when the oath was administered.
¶ 8. Certain prospective jurors were then brought into the courtroom for individual questioning in the presence of the court, Lepsch, and his attorneys. A number of prospective jurors were excused. Next, remaining prospective jurors were brought into the courtroom as a group and questioned in the presence of the court, Lepsch, and his attorneys. Finally, Lepsch and the State were each given six peremptory strikes and a panel of 15 jurors was selected.
¶ 9. From Wednesday, July 24, 2013, to Friday, July 26, 2013, and from Monday, July 29, 2013, to Tuesday, July 30, 2013, Lepsch was tried before the jury. There is no dispute that this jury was properly sworn by a clerk in Lepsch's presence in court at the start of his trial. On July 30, 2013, the jury returned a [109]*109verdict of guilty as to all counts charged. On September 3, 2013, the circuit court sentenced Lepsch to two life sentences without extended supervision for the homicide charges, a 40-year term of imprisonment for the armed robbery charge, and a 10-year term of imprisonment for the possession of a firearm by a felon charge, all to be served consecutively. On September 4, 2013, the judgment of conviction was entered.
¶ 10. On November 25, 2013, Lepsch filed a notice of intent to seek postconviction relief, and on July 15, 2014, Lepsch filed a postconviction motion for a new trial. In his motion he challenged the convictions asserting that he received ineffective assistance of counsel. On September 4, 2014, the circuit court held a Machner hearing on Lepsch's motion. See State v. Machner, 92 Wis. 2d 797, 285 N.W.2d 905 (Ct. App. 1979). On November 14, 2014, the circuit court denied Lepsch's motion.
¶ 11. On December 2, 2014, Lepsch filed a notice of appeal. On November 19, 2015, the court of appeals affirmed the circuit court's judgment of conviction and order denying postconviction relief in an unpublished, per curiam opinion. Lepsch, unpublished slip op., ¶ 1.
¶ 12. On December 4, 2015, Lepsch filed a petition for review in this court. On May 11, 2016, this court granted the petition.
II. STANDARD OF REVIEW
¶ 13. "A claim of ineffective assistance of counsel is a mixed question of fact and law." State v. Ortiz-Mondragon, 2015 WI 73, ¶ 30, 364 Wis. 2d 1, 866 N.W.2d 717 (quoting State v. Carter, 2010 WI 40, ¶ 19, 324 Wis. 2d 640, 782 N.W.2d 695). We review the [110]*110circuit court's findings of fact under a clearly erroneous standard, but independently determine the legal question of whether counsel's assistance was ineffective. Id. (quoting Carter, 324 Wis. 2d 640, ¶ 19).
¶ 14. We "review [] constitutional questions, both state and federal, de novo." State v. Lagrone, 2016 WI 26, ¶ 18, 368 Wis. 2d 1, 878 N.W.2d 636 (quoting State v. Schaefer, 2008 WI 25, ¶ 17, 308 Wis. 2d 279, 746 N.W.2d 457).
¶ 15. Other applicable standards will be discussed below.
III. ANALYSIS
¶ 16. Lepsch's appeal focuses on his ineffective assistance of counsel claim.5 Lepsch possesses state and federal constitutional rights to the effective assistance of counsel. U.S. Const, amends. VI, XIV; Wis. [111]*111Const. art. I, § 7;6 Strickland v. Washington, 466 U.S. 668, 686 (1984); State v. Starks, 2013 WI 69, ¶ 54, 349 Wis. 2d 274, 833 N.W.2d 146. "The standard for determining whether counsel's assistance is effective under the Wisconsin Constitution is identical to that under the federal Constitution." State v. Thiel, 2003 WI 111, [112]*112¶ 18 n.7, 264 Wis. 2d 571, 665 N.W.2d 305. "First, the defendant must prove that counsel's performance was deficient. Second, if counsel's performance was deficient, the defendant must prove that the deficiency-prejudiced the defense." Carter, 324 Wis. 2d 640, ¶ 21 (citation omitted). With regard to the first part of this test, ''[c]ounsel's conduct is constitutionally deficient if it falls below an objective standard of reasonableness." Thiel, 264 Wis. 2d 571, ¶ 19 (citing Strickland, 466 U.S. at 688). With regard to the second part of this test, "the defendant must show that 'there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome.' " Id., ¶ 20 (quoting Strickland, 466 U.S. at 694).
A. Impartial Jury
¶ 17. In Lepsch's first ineffective assistance of counsel claim, Lepsch argues his attorneys were ineffective in failing to raise jury bias issues during jury selection. As a result, he claims nine of the jurors in his case were biased, which denied him his right to an impartial jury under the Wisconsin and federal constitutions. Lepsch bases this challenge on various answers given in response to four questions on the pre-trial questionnaires completed by the prospective jurors. He argues that his attorneys were ineffective for "failing to sufficiently examine and challenge prospective jurors for cause."
¶ 18. We now present the four questions at issue. Question 30 of the questionnaire reads as follows: "You will be hearing testimony from several police officers in this case. Do you think you would give police officers more credibility, less credibility or the same amount of credibility as other witnesses who were not police [113]*113officers?" The question contained spaces for the prospective juror to check "more credibility," "less credibility," or "the same credibility," and asked the prospective juror to explain his or her answer. Seven of the twelve jurors who sat on Lepsch's case answered "more credibility."7
¶ 19. Question 35 of the questionnaire contained the following questions, among others: (1) "Have you ever expressed the opinion that Mr. Lepsch was guilty?"; (2) "Do you have any feelings at this time that you have made up your mind as to Mr. Lepsch's guilt?"; and (3) "IF YES, would you have any difficulty putting these feelings out of your mind if you were chosen to be a juror?". Each question was followed by spaces for the prospective juror to check "Yes" or "No." Four of the twelve jurors on Lepsch's jury answered that they had expressed the opinion that Mr. Lepsch was guilty.8 Three of these same four jurors answered that they "ha[d] . . . feelings" that they had made up their mind as to Lepsch's guilt.9 Each of these three then answered that they would not have any difficulty putting the feelings out of their mind if they were chosen to be a juror.
¶ 20. Question 32 asked, "Do you have any problem with the legal proposition that a defendant must be presumed innocent unless and until the prosecution can prove he or she is guilty?" And Question 34 asked a related question: "Do you think if the State goes to the trouble of bringing someone to trial, the person is probably guilty?" Both questions left spaces for the prospective juror to check "Yes" or "No," and both [114]*114questions asked for the prospective juror to explain his or her answer. One juror answered "No" to Question 32 (regarding the presumption of innocence) but then explained his answer as follows: "In general, no. But I do not believe that this should be the case 100% of the time. I believe that there are cases in which there is immediate and overwhelming evidence (i.e., physical evidence, audio/video evidence, confessions, etc.) should be presumed guilty until trial [sic]." The same juror answered Question 34 (relating to whether a person brought to trial is probably guilty) as follows: "Probably? Yes. Definitely? Not necessarily. I would hope that the courts would not bring someone in just so they have someone to try. I would hope there would at least be a fair amount of evidence or cause before bringing someone in."10
¶ 21. Before addressing the deficiency and prejudice prongs of Lepsch's ineffective assistance of counsel claim, we set forth the law governing juror bias. "The United States Constitution and Wisconsin's Constitution guarantee an accused an impartial jury." State v. Mendoza, 227 Wis. 2d 838, 847, 596 N.W.2d 736 (1999) (citing U.S. Const. amends. VI and XTV; Wis. Const. art. I, § 7).11 "To be impartial, a juror must be indifferent and capable of basing his or her verdict upon the evidence developed at trial." State v. Faucher, 227 Wis. 2d 700, 715, 596 N.W.2d 770 (1999) (citing Irvin v. Dowd, 366 U.S. 717, 722 (1961)).
¶ 22. "Reviewing courts are properly resistant to second-guessing the trial judge's estimation of a juror's [115]*115impartiality, for that judge's appraisal is ordinarily influenced by a host of factors impossible to capture fully in the record—among them, the prospective juror's inflection, sincerity, demeanor, candor, body language, and apprehension of duty." Skilling v. United States, 561 U.S. 358, 386 (2010). "Prospective jurors are presumed impartial" and Lepsch "bears the burden of rebutting this presumption and proving bias." State v. Funk, 2011 WI 62, ¶ 31, 335 Wis. 2d 369, 799 N.W.2d 421 (quoting State v. Louis, 156 Wis. 2d 470, 478, 457 N.W.2d 484 (1990)). "We have recognized three types of bias: (1) statutory bias; (2) subjective bias; and (3) objective bias." State v. Smith, 2006 WI 74, ¶ 19, 291 Wis. 2d 569, 716 N.W.2d 482 (citing Faucher, 227 Wis. 2d at 716). Lepsch argues that the jurors he challenged were subjectively and objectively biased.
¶ 23. Subjective bias refers to "bias that is revealed through the words and the demeanor of the prospective juror." Faucher, 227 Wis. 2d at 717. "[T]he circuit court sits in a superior position to assess the demeanor and disposition of prospective jurors, and thus, whether they are subjectively biased." Id. at 718. Accordingly, "we will uphold the circuit court's factual finding that a prospective juror is or is not subjectively biased unless it is clearly erroneous." Id.
¶ 24. The concept of objective bias relates to the question of "whether [a] reasonable person in the individual prospective juror's position could be impartial." Id.
Objective bias ... is a mixed question of fact and law. "[A] circuit court's findings regarding the facts and [116]*116circumstances surrounding voir dire and the case will be upheld unless they are clearly erroneous. Whether those facts fulfill the legal standard of objective bias is a question of law." Although we do not defer to a circuit court's decision on a question of law, where the factual and legal determinations are intertwined as they are in determining objective bias, we give weight to the circuit court's legal conclusion. We have said that we will reverse a circuit court's determination in regard to objective bias "only if as a matter of law a reasonable judge could not have reached such a conclusion."
Funk, 335 Wis. 2d 369, ¶ 30 (citations omitted) (quoting Faucher, 227 Wis. 2d at 720-21).
f 25. In order to succeed on his ineffective assistance of counsel claim, Lepsch must prove that his attorneys acted deficiently during jury selection and that he was prejudiced by this performance. Our review demonstrates that none of the jurors who sat on Lepsch's case were biased, either subjectively or objectively, and that Lepsch was therefore not prejudiced by the performance of his attorneys, even if the performance was deficient in some respect (a question we need not decide).
¶ 26. The circuit court below explained, in denying Lepsch's postconviction motion:
From the court's position of being able to best determine juror bias, the court is absolutely convinced that each juror was able to put any potential biases out of their minds. The court is absolutely certain that Lepsch was tried by a fair and impartial jury who decided the case based solely on the evidence before them. The court is unequivocally convinced that the jury agonized over its decision and gave Lepsch every benefit of the doubt.
[117]*117f 27. Lepsch cannot establish ineffective assistance because he cannot prove either objective or subjective bias. Seven of Lepsch's jurors stated in the questionnaire that they would give police officers more credibility than witnesses who were not police officers.12 Five of these jurors, however, were specifically questioned on that answer, and the lawyers and/or the court examined this belief and ensured that the jurors could decide the case impartially. To take just one example,13 the court asked R.F. the following with regard to law enforcement officers:
[T]he question is, once they are sitting in the seat you're sitting in and they are a witness, can you judge them, the credibility, what they say based upon those things that we as human beings use as intangibles to determine people's credibility and not just cut them slack because they happen to be law enforcement?
R.F. responded, "Yes, Your Honor." The court then confirmed, "So you can — you can look at them as you would any other witness?" R.F. responded, "Yes." Given our deference to the circuit court on these types of questions, we will not displace the circuit court's conclusion that these jurors were not biased when they sat on Lepsch's case.
¶ 28. J.A. and D.M. are the two jurors who were not specifically questioned on this point. However, other aspects of the jury selection process provide [118]*118support for the circuit court's rejection of Lepsch's claims of bias. Both J.A. and D.M. checked "No" on their questionnaires next to the question, "Is there any reason why you could not be impartial in this case?" And D.M. stated elsewhere on his questionnaire, "I believe in facts, not people." See, e.g., Griffin v. Bell, 694 F.3d 817, 823-24) (7th Cir. 2012) ("[Juror] Carel, of course, never said that she could not be fair. At most, she indicated that her first inclination, if faced with conflicting stories from a police officer and a fourteen-year-old boy, would 'most likely' be to believe the officer. ... In this case, although [juror] Carel expressed an initial inclination that police officers are more credible than teenagers, she never expressed an irrational or unshakeable bias that indicated an inability or unwillingness to faithfully and impartially apply the law."); United States v. Ricketts, 146 F.3d 492, 496 (7th Cir. 1998) ("In the abstract, it is certainly not unreasonable for an ordinary person to say she would generally tend to believe a prison guard over a prison inmate. But that certainly doesn't mean that in a given case, after hearing sworn testimony under oath and considering all the facts and circumstances, that that same juror would automatically believe a given guard over a given inmate. Generalized questions of the sort asked here are a slim basis upon which to base a challenge for cause.").
¶ 29. Further, both J.A. and D.M. were present during questioning of the jurors as a group. Given the general tenor of voir dire, the prospective jurors could not have "fail[ed] to recognize that bias in favor of law enforcement officials was inappropriate." United States v. Lancaster, 96 F.3d 734, 742-43 (4th Cir. 1996) (reaching this conclusion in part because the court had inquired about "bias in favor of law enforcement offi[119]*119cials resulting from a relationship with a relative or friend in law enforcement"). The defense informed the prospective jurors, "[T]here's no wrong answers, and I want you guys to talk to me. We're after an unbiased jury here, and it's okay to have biases. We all have them." Topics touched on during questioning by the defense were whether the police can make mistakes, whether it is important that law enforcement follow procedures, whether police "ever let bias get in the way of what they're looking for," whether "we tend to trust professionals [including police] a little more than we should sometimes," and how to determine whether a professional such as a policeman "has the right training or experience."
¶ 30. Moreover, earlier in voir dire, the State explained to the prospective jurors, "both sides want people who are fair, objective," later adding:
[B]y now you've gotten some pretty good ideas through the questionnaires and all the questioning of the kind of things we want to know about people. Is there anything that anybody hasn't asked and you've just been sitting here waiting, why don't they ask me this because I really shouldn't be on this jury, but nobody's asked me why? Is there anything that we haven't asked at this point, anyone who says, I should not be here; I can't be fair; and we just haven't asked the right question yet?
There was no response. See Lancaster, 96 F.3d at 743 ("Under these circumstances, the district court's final voir dire question—'Ladies and Gentlemen, do you know of any reason, is there anything at all any of you know of that would make it difficult for you to sit as an impartial juror in this case?'—could not have failed to elicit an affirmative response from any member of the venire harboring a bias in favor of law enforcement [120]*120officials." (citation omitted)). Again, given the standard of review, we are not in a position to disturb the circuit court's judgment that no bias existed on Lepsch's jury in this regard. Thus, even assuming Lepsch's attorneys should have examined this matter further during jury selection in some way, Lepsch has not proven that he was prejudiced by the performance.
¶ 31. Lepsch's claims of bias regarding jurors who said they had expressed an opinion on Lepsch's guilt or had made up their mind as to Lepsch's guilt are also unpersuasive. Each of the three jurors who stated "Yes" on their questionnaires when asked, "Do you have any feelings at this time that you have made up your mind as to Mr. Lepsch's guilt?" also stated "No" in response to the question of whether they would have any difficulty putting these feelings out of their minds as jurors. All four who stated they had "ever expressed the opinion that Mr. Lepsch was guilty" were individually questioned in some manner as to whether they could base their decisions on the evidence; each juror verified that he or she could do so. Lepsch has not demonstrated that the circuit court's findings regarding bias should be overturned as to these jurors, and he has not shown prejudice with respect to his attorneys' questioning of these jurors.
f 32. Finally, the juror who qualified his agreement with the presumption of innocence and who agreed that if the State goes to the trouble of bringing someone to trial, the person is probably guilty, was informed that he would be instructed about the presumption of innocence and that he had to "start out with looking as Mr. Lepsch as he is innocent," that he is "innocent as he sits here today." The juror was asked [121]*121if he was "okay with that principle," and the juror affirmed that he was. Again, we see no prejudice resulting from the questioning of this juror.
¶ 33. Before proceeding further, we note that Lepsch takes issue with our discussion of the law on juror impartiality, contending that it is contrary to federal law insofar as it does not require a "final, unequivocal" swearing by a juror that he or she can set aside his or her beliefs and opinions and decide the case solely on the evidence. Lepsch relies predominantly on Patton v. Yount, 467 U.S. 1025 (1984), citing a passage explaining that in a "federal habeas corpus case in which the partiality of an individual juror is placed in issue," the question before the reviewing court "is plainly one of historical fact: did a juror swear that he could set aside any opinion he might hold and decide the case on the evidence, and should the juror's protestation of impartiality have been believed." Yount, 467 U.S. at 1036.
¶ 34. We disagree with Lepsch that Supreme Court case law14 dictates that a bright-line rule be applied in cases involving a defendant's claim he did not receive an impartial jury. First, it is important to consider the context of the single line in Yount cited by Lepsch. The Supreme Court was rejecting, on federal habeas review, the view of the court of appeals below it [122]*122that "the question whether jurors have opinions that disqualify them is a mixed question of law and fact" such that "the presumption of correctness due a state court's factual findings under" federal habeas review was inapplicable. Id. at 1028-31,1036. Its focus in that passage was not the definition of the substantive standard, but instead the notion that application of the relevant standard was "not one of mixed law and fact" and that "the statutory presumption of correctness" thus applied to the trial court's determinations. See id. at 1036-38.
¶ 35. And indeed, the Yount Court later restated the applicable inquiry on habeas review as "whether there is fair support in the record for the state courts' conclusion that the jurors here would be impartial," adding,
Jurors .. . cannot be expected invariably to express themselves carefully or even consistently. Every trial judge understands this, and under our system it is that judge who is best situated to determine competency to serve impartially. The trial judge properly may choose to believe those statements that were the most fully articulated or that appeared to have been least influenced by leading.
Yount, 467 U.S. at 1038-39 (emphasis added). This suggests an amount of leeway inconsistent with the rigid rule proposed by Lepsch. See also id. at 1039-40 ("[I]n the case of alternate juror Pyott, we cannot fault the trial judge for crediting her earliest testimony, in which she said that she could put her opinion aside '[i]f [she] had to,' rather than the later testimony in which defense counsel persuaded her that logically she would need evidence to discard any opinion she might have."); id. at 1039 ("We think that the trial judge's decision to seat [juror] Hrin, despite early ambiguity in [123]*123his testimony, was confirmed after he initially denied the challenge. Defense counsel sought and obtained permission to resume cross-examination. In response to a question whether [juror] Hrin could set his opinion aside before entering the jury box or would need evidence to change his mind, the juror clearly and forthrightly stated: T think I could enter it [the jury box] with a very open mind. I think I could . . . very easily. To say this is a requirement for some of the things you have to do every day.' ").
f 36. Recent Supreme Court case law supports our understanding of Yount. In Skilling the Supreme Court explained that "[n]o hard-and-fast formula dictates the necessary depth or breadth of voir dire," following that statement with a quotation from one of its earlier cases: "Impartiality is not a technical conception. It is a state of mind. For the ascertainment of this mental attitude of appropriate indifference, the Constitution lays down no particular tests and procedure is not chained to any ancient and artificial formula." Skilling, 561 U.S. at 386 (emphasis added) (quoting United States v. Wood, 299 U.S. 123, 145-46 (1936)). Finally, Lepsch does not direct us to any Supreme Court cases explicitly applying his interpretation of the putative test from Yount. We agree with Lepsch that a prospective juror must be able to "set aside any opinion he might hold and decide the case on the evidence." Yount, 467 U.S. at 1036. But, as a general matter, a circuit court need not use or obtain any magic words in determining whether this requirement has been met.
¶ 37. In sum, Lepsch has not provided sufficient reason to upset the circuit court's determination that none of the jurors who sat on Lepsch's case were [124]*124biased, either subjectively or objectively. Thus, even assuming that Lepsch's counsel performed deficiently at voir dire, Lepsch has failed to demonstrate that he was prejudiced by this performance and his ineffective assistance of counsel claim must be rejected. C.f., e.g., Peterson v. State, 154 So. 3d 275, 282 (Fla. 2014) (per curiam) ("Peterson cannot demonstrate prejudice because no biased juror sat on his jury."); State v. Erickson, 227 Wis. 2d 758, 774, 596 N.W.2d 749 (1999) ("more than rank speculation" is needed "to satisfy the prejudice prong").
f 38. Lepsch also maintains that his right to due process of law was denied because of "circumstances that create [d] the 'likelihood or the appearance of bias,' " Peters v. Kiff, 407 U.S. 493, 502 (1972) (plurality opinion), and because the circuit court "fail[ed] to conduct a sufficient inquiry regarding such circumstances." Lepsch's claim is stated in broad terms and without adequate legal development, and we reject it. As the circuit court explained:
The court and both parties were aware that this case was going to be well-known in the community long before the trial ever began. For that exact reason, the court took extra precaution to ensure an impartial jury, beyond what it would do for most jury trials. The extensive questionnaire sent out to the jurors was used to eliminate 24 jurors who exhibited a bias indicating they could not sit as objective jurors, before they ever reported for jury duty and by the agreement of both parties. After those potential jurors had been eliminated, the potential jurors who reported were brought into the courtroom one at a time. They were questioned by the court and both parties regarding pretrial publicity, their ability to decide the case only on the evidence presented, and about any potentially [125]*125problematic answers on their questionnaire. More jurors were excused during this process. Then voir dire began as it normally would.
(Footnote omitted) (citations omitted). The circuit court's careful administration of jury selection and the verbal in-person questioning that took place cured any possibility of the "likelihood or the appearance of bias" at least as outlined in the arguments Lepsch has made.15 We conclude that he was not denied due process.16
B. Administration of the Oath to the Prospective Jurors
¶ 39. Next, Lepsch argues that the swearing of prospective jurors outside of his presence by the La Crosse County Clerk of Courts violated his rights to be present at all critical stages of a criminal proceeding, to receive a public trial, and to receive a trial by an impartial jury. He contends that his trial attorneys [126]*126were ineffective in failing "to ensure that the trial court properly administered the oath to the jury venire in Lepsch's presence."17
¶ 40. To be clear, Lepsch does not dispute that the jury he ultimately received was properly sworn by a clerk in Lepsch's presence in court at the start of his trial. See Wis. Stat. § 756.08 (2013-14). Instead, he is asserting alleged deficiencies with regard to the administration of the oath to the prospective jurors prior to questioning of the prospective jurors by the court, the State, and Lepsch's counsel.
¶ 41. Lepsch's briefing essentially discusses his constitutional rights at voir dire. We are thus able to immediately dismiss most of Lepsch's argument because he was, in fact, present at voir dire. Black's Law Dictionary defines "voir dire" as "[a] preliminary examination of a prospective juror by a judge or lawyer to decide whether the prospect is qualified and suitable to serve on a jury," adding that "[l]oosely, the term refers to the jury-selection phase of trial." Voir dire, Black's Law Dictionary 1805 (10th ed. 2014). We decline to adopt Lepsch's more expansive conception of voir dire, according to which proceedings involving management of the jury pool occurring prior to the entry of the prospective jurors into the courtroom are given consti[127]*127tutional significance. Lepsch has not sufficiently explained why voir dire encompasses the administration of the oath to the prospective jurors any more than it encompasses the completion of the questionnaires by the prospective jurors prior to the start of trial.
¶ 42. Similarly, we reject as meritless Lepsch's contention that the circuit court, not a clerk, was required by statute to administer the oath. Lepsch cites Wis. Stat. § 805.08(1) (2013-14), which states that:
The court shall examine on oath each person who is called as a juror to discover whether the juror is related by blood, marriage or adoption to any party or to any attorney appearing in the case, or has any financial interest in the case, or has expressed or formed any opinion, or is aware of any bias or prejudice in the case.
Wis. Stat. § 805.08(1) (2013-14). In response, the State cites Wis. Stat. § 756.001(5) (2013-14), which states that "[t]he clerk of circuit court, if delegated by and under the supervision of the judge responsible for administering the jury system, may select and manage juries under policies and rules established by the judges in that circuit court." Lepsch does not appear to have much of a reply to this argument. Nor does Lepsch explain how he was harmed by the putative error, other than to point to his other constitutional claims. We dismiss Lepsch's argument regarding the identity of the administrator of the oath as undeveloped. See State v. Gracia, 2013 WI 15, ¶ 28 n.13, 345 Wis. 2d 488, 826 N.W.2d 87 ("[W]e do not usually address undeveloped arguments.").
¶ 43. More generally, however, Lepsch's line of argument relating to the ad ministration of the oath to [128]*128the prospective jurors "ignores the[] day-to-day realities of courtroom life and undermines society's interest in the administration of criminal justice." Rushen v. Spain, 464 U.S. 114, 119 (1983) (per curiam). Clerks play a critical role in the daily functioning of our court systems, and the procedures challenged by Lepsch doubtlessly occur in courthouses throughout the state. Were we to accept Lepsch's arguments, we would be casting doubt on the clerks' capacity to act, as clerks routinely do, in the summoning and preparing of prospective jurors for the circuit courts of the state. See, e.g., Wis. Stat. § 756.04(9)(a) (2013-14) ("Prospective juror lists; number; how compiled. . . . During each year, the clerk of circuit court shall provide the court with a sufficient number of names of prospective jurors to meet the needs of the court."); § 756.05 (2013-14) ("Jury summons, when and how issued. At least 12 days before the first day on which a jury is required to be present, to create the jury venire, the clerk of circuit court shall randomly select a sufficient number of prospective jurors from the jury array created under s. 756.04(9) who shall be summoned to appear before the court at an appropriate time for jury service."); § 756.06(1) (2013-14) ("Jury selection. (1) Whenever an issue is to be tried before a jury, the clerk of circuit court shall randomly select names from the jury venire until the desired number is obtained to create the jury panel."); § 756.07 (2013-14) ("Insufficient jurors. When a sufficient number of jurors cannot be obtained for a trial from the jury venire supplied by the clerk of circuit court, the court may order the sheriff to bring before the court persons in the vicinity for determination by the court of their qualification and ability to serve as jurors for the particular trial."). We decline to do so today.
[129]*129¶ 44. Even assuming for the sake of argument that error existed, Lepsch still cannot succeed. We first address Lepsch's putative right to be present. Although he does not cite any applicable constitutional provisions, Lepsch includes a pair of court of appeals decisions in his brief containing the proposition that "[t]he right to be present at jury selection is . .. protected by the Sixth and Fourteenth Amendments of the United States Constitution and Article I, Section 7 of the Wisconsin Constitution."18 State v. Harris, 229 Wis. 2d 832, 839, 601 N.W.2d 682 (Ct. App. 1999); see State v. Talley, 2001 WI App 236, ¶ 6, 248 Wis. 2d 505, 635 N.W.2d 807.19 Additionally, Wis. Stat. § 971.04(l)(c) (2013-14) states that, subject to certain exceptions, "the defendant shall be present: . . . During voir dire of the trial jury." Wis. Stat. § 971.04(1)(c) (2013-14).
¶ 45. We observe that the parties at times discuss this claim in terms of harmless error analysis. And indeed, there is case law supporting such an approach. See, e.g., Talley, 248 Wis. 2d 505, ¶ 7 ("[Deprivation of.. . the defendant's right to be present.. . during voir dire is reviewed on appeal for harmless error." (citing Harris, 229 Wis. 2d at 839-40)); Spain, 464 U.S. at 117-18 n.2 ("right to be present during all critical stages [130]*130of the proceedings" is "subject to harmless-error analysis"). Yet, without much explanation, the parties also address the claim as one of ineffective assistance of counsel.
¶ 46. We note that under a harmless error analysis, the State would bear the burden of establishing that any error was harmless because it stands to benefit from such an error. See, e.g., State v. Martin, 2012 WI 96, ¶ 45, 343 Wis. 2d 278, 816 N.W.2d 270. Conversely, pursuant to an ineffective assistance of counsel analysis, the burden would be on Lepsch to establish ineffective assistance of counsel. See Carter, 324 Wis. 2d 640, f 21. Nevertheless, whether the claim is addressed under harmless error review or under the rubric of ineffective assistance of counsel, Lepsch is not entitled to relief.
¶ 47. Even if Lepsch had statutory and constitutional rights to be present at the swearing of the prospective jurors, any error stemming from Lepsch's absence was harmless. The La Crosse County Clerk of Courts swore in an affidavit:
I was present with prospective jurors on July 23, 2013 in the matter of State v. Lepsch ... in the jury assembly room for jury selection. .. . Prior to having the jurors transported to the courtroom via elevator to be individually questioned, I performed the oath as required with all prospective jurors.
The circuit court below found that the prospective jurors were indeed given the oath. Further, as discussed, Lepsch has not demonstrated that his jury was anything less than impartial. We agree with the State that any error was harmless, and Lepsch does not give us reason to conclude otherwise. See, e.g., State v. [131]*131Deadwiller, 2013 WI 75, ¶ 41, 350 Wis. 2d 138, 834 N.W.2d 362 (quoting Martin, 343 Wis. 2d 278, ¶ 45) ("[A]n error is harmless if the beneficiary of the error proves beyond a reasonable doubt that the error complained of did not contribute to the verdict obtained.").20
¶ 48. For similar reasons, under an ineffective assistance of counsel analysis, we conclude that Lep-sch's attorneys' failure to object to Lepsch's absence at the swearing of the prospective jurors did not prejudice21 Lepsch even if this failure constituted deficient performance. Thiel, 264 Wis. 2d 571, ¶ 20 ("In order to demonstrate that counsel's deficient performance is constitutionally prejudicial, the defendant must show that 'there is a reasonable probability that, but for counsel's unprofessional errors, the result of the proceeding would have been different. A reasonable prob[132]*132ability is a probability sufficient to undermine confidence in the outcome.'" (quoting Strickland, 466 U.S. at 694)).22
¶ 49. Second, we conclude that, contrary to Lep-sch's contention, Lepsch has forfeited his claim that the swearing of prospective jurors outside of his presence violated his right to receive a public trial by failing to raise an objection below. "The Sixth Amendment to the United States Constitution provides an accused the right to a public trial.... The Supreme Court has determined that the public trial right is applicable to the states based on its incorporation into the Fourteenth Amendment."23 State v. Pinno, 2014 WI 74, ¶ 40, 356 Wis. 2d 106, 850 N.W.2d 207 (citing Presley v. Georgia, 558 U.S. 209, 211-12 (2010) (per curiam)). In Pinno we "decline [d] to allow defendants who failed to object to the closure of a courtroom to raise that issue for the first time after the trial is over," and concluded that "the Sixth Amendment right to a public trial may be forfeited when a defendant knows that the judge has ordered the public to leave the courtroom but does not object." Pinno, 356 Wis. 2d 106, ¶ 63.
¶ 50. Lepsch argues Pinno is inapposite because "[a]t no time during the proceedings did the trial court inform Lepsch that the oath to the prospective jurors would be administered in the 'jury assembly room' by the clerk rather than the judge in open court." We agree with the statement of the court of appeals: "Clearly, Lepsch was aware at the time of the jury voir [133]*133dire that the oath had not been administered to the jury venire in his presence in open court. Lepsch has not provided any support for his assertion that he was unaware of the manner in which the oath had been administered to the jury venire at the time of voir dire." Lepsch, unpublished slip op., ¶[ 7.24
¶ 51. Lepsch argues Pinno should not be applied because "Lepsch can show actual prejudice." Lepsch argues that "[t]o the extent that the administration of the oath was defective, which Lepsch maintains it was, it precluded him from receiving a trial by an impartial jury." It is not clear what Lepsch means by this line of reasoning given that Pinno's discussion of prejudice occurred in the ineffective assistance of counsel context, see Pinno, 356 Wis. 2d 106, ¶¶ 81-91, and Lepsch seemingly makes this argument independent of any ineffective assistance of counsel claim.
¶ 52. In any event, the argument cannot succeed because the manner of the administration of the oath did not "preclude D [Lepsch] from receiving a trial by an impartial jury." Lepsch states that "[i]f a juror is not sworn or not sworn properly, then that juror cannot be deemed to be an 'impartial' juror for the 6th Amendment or Article 1, Section 7 [of the Wisconsin Constitution]." But this case does not involve prospective jurors who were not sworn, as the affidavit of the La Crosse County Clerk of Courts confirms. And Lepsch does not explain why the two potential defects he identifies—that the oath was administered by a clerk rather than the circuit court and that Lepsch was absent at the administration of the oath—means that the jury was not "sworn properly" for purposes that [134]*134would be relevant to the impartiality of his jury. In other words, Lepsch's statement that the manner of administration of the oath meant that his jury was not impartial is simply conclusory.25 Without more, we are unable to conclude that Lepsch's jury was not impartial. Accordingly, we apply Pinno and conclude that Lepsch's claim is forfeited.26
¶ 53. Having concluded that Lepsch's claim is indeed forfeited, we proceed to Lepsch's contention that his attorneys' failure to "ensure that the trial court properly administered the oath to the jury venire in Lepsch's presence constituted ineffective assistance of counsel." With regard to the prejudice prong of the analysis, Lepsch's argument consists of two sentences. First, "In terms of prejudice, Lepsch suffered actual prejudice in that an improperly sworn jury did not and could not constitute an impartial jury." We have already [135]*135rejected this argument. Second, "In the alternative, this Court should presume prejudice given that the failure to properly administer the oath to prospective jurors amounted to structural error." We read this vague argument to refer back to Lepsch's earlier argument: "[T]he improper administration of the oath created two different structural errors. The first directly pertained to Lepsch's right to a public trial and the second pertained to Lepsch's right to an impartial jury." Because we have concluded that Lepsch's right to an impartial jury was not violated by the administration of the oath by the clerk outside of his presence, we need only address ineffective assistance as it pertains to Lepsch's first claim related to his right to a public trial.
¶ 54. In Pinno we concluded that a presumption of prejudice was not appropriate in cases involving "the denial of the right to a public voir dire." Pinno, 356 Wis. 2d 106, ¶ 85. Below, the court of appeals remarked that Lepsch had "not developed an argument distinguishing the claimed structural errors in this case from the errors in Pinno, id., ¶¶ 83-86, which were deemed not to give rise to a presumption of prejudice." Lepsch, unpublished slip op., ¶ 8. Lepsch has not altered his approach before this court. Therefore, we reject his argument. Finally, we note that Lepsch has not demonstrated that he was prejudiced in any other way by his attorneys' failure to object to the manner of the administration of the oath. We conclude that he was not denied the effective assistance of counsel with regard to this claim.27
[136]*136C. Peremptory Strikes
¶ 55. Finally, Lepsch argues that the circuit court's failure to award him the proper number of peremptory strikes, along with its failure to strike certain jurors for cause, violated his rights to due process of law and to an impartial jury. Lepsch argues that he was given six peremptory strikes rather than the seven to which he was entitled, and that he was forced to exhaust his strikes on jurors who should have been dismissed for cause, such that he was unable to dismiss the jurors who actually sat on his jury. He contends that his attorneys were ineffective in failing to object to receiving an incorrect number of peremptory strikes and in failing to challenge certain jurors for cause.
¶ 56. There seems to be no dispute that both Lepsch and the State were entitled to seven peremptory strikes under the law but were only given six each. See Wis. Stat. § 972.03 (2013-14). Nevertheless, we conclude, again, that even if Lepsch's attorneys performed deficiently in not raising the appropriate objections and challenges, Lepsch was not prejudiced by the performance.
¶ 57. As has been stated, Lepsch has not shown that any of his jurors were biased. With regard to Lepsch's complaint that he was entitled to an additional peremptory strike, this case is therefore not unlike Erickson, where both the State and the defendant were granted four peremptory strikes rather than the seven to which they were entitled. Erickson, 227 Wis. 2d at [137]*137762. Analyzing the defendant's ineffective assistance of counsel claim, we "decline [d] to presume prejudice every time there [was] a denial of an equal number of peremptory strikes to both the defense and the prosecution" and where "[t]here [was] little doubt that [the defendant] was judged by an impartial jury." Id. at 761, 777. We then concluded that a determination that actual prejudice existed was inappropriate: "In the end, we can do no better than speculate on what would have been the result of [the defendant's] trial had the circuit court not erred, which is also the best that Erickson can offer." Id. at 774. The same analysis applies in this case.
¶ 58. Second, assuming Lepsch was forced to use peremptory strikes on jurors who should have been challenged for cause, the error did not in fact result in a biased juror sitting on Lepsch's jury. Consequently, the ineffective assistance claim Lepsch has made28 [138]*138fails. See State v. Traylor, 170 Wis. 2d 393, 400, 489 N.W.2d 626 (Ct. App. 1992) ("Traylor cannot prove prejudice unless he can show that the exhaustion of peremptory challenges left him with a jury that included an objectionable or incompetent member. Wisconsin's longstanding rule is that where a fair and impartial jury is impaneled, there is no basis for concluding that a defendant was wrongly required to use peremptory challenges." (citation omitted)).
IV. CONCLUSION
¶ 59. We conclude that each of Lepsch's claims fails, and that he is not entitled to a new trial. Consequently, we affirm the decision of the court of appeals.
By the Court.—The decision of the court of appeals is affirmed.
