[1271]*1271HENRY, Circuit Judge.
This case requires us to determine whether a majority vote for a representative union was actionably clouded by a sustained or inflammatory appeal to religious bias. We may set aside the certification of the election only if the National Labor Relations Board (“the Board”) incorrectly applied the law or its findings are not supported by substantial evidence. 29 U.S.C. § 160(e); NLRB v. Velocity Express, Inc., 434 F.3d 1198, 1201 (10th Cir. 2006). Consequently, the Board has “wide discretion” in judging the fairness of an election, and a party objecting to pre-election conduct bears a “heavy burden” to prove that there has been prejudice to an election’s fairness. M & M Supermarkets, Inc. v. NLRB, 818 F.2d 1567, 1573 (11th Cir.1987).
In this appeal, Honeyville Grain asks us to set aside an election in which its truck drivers at a California facility voted in favor of a union to represent them. Honeyville contends that the union’s agents made inappropriate remarks at a union meeting, five days before the election, by referring to the religious beliefs of the company’s owners in an attempt to inflame the drivers’ religious prejudices. The Board certified the union as the exclusive bargaining agent of the employees, and Honeyville subsequently refused to bargain with the union. The Board later ordered Honeyville to cease and desist from refusing to bargain. In response, Honey-ville petitions for review of the Board’s order, and the Board cross-appeals to enforce the order. We exercise jurisdiction under 29 U.S.C. § 160(e) and (f). Based on our deferential standard of review, we deny Honeyville’s petition for review and enforce the order of the Board.
I.BACKGROUND
Honeyville Grain is a Utah corporation with facilities in California and Utah. It processes and distributes food products, and it employs truck drivers to deliver its products. In February 2002, the Local 166 of the International Brotherhood of Teamsters, AFL-CIO (“the Union”) petitioned the Board for an election in a unit of Honeyville’s full-time and part-time truck drivers at the Rancho Cucamonga, California facility. “[T]he Board not only conducts elections, but it also oversees the propaganda activities of the participants in the election to insure that the voters have the opportunity of exercising a reasoned, untrammeled choice for or against labor organizations seeking representation rights.” Sewell Mfg. Co., 138 NLRB 66, 69, 1962 WL 16079 (1962).
The Board conducted a secret-ballot election at Rancho Cucamonga on April 12, 2002. All thirty-two eligible voters cast ballots; twenty-three voted in favor of the Union, seven voted against the Union, and two ballots were challenged. Later that month, Honeyville filed ten objections to the election. Relevant to this appeal, Honeyville objected to comments made in a meeting held at the Union’s office five days before the election; twenty to twenty-five of the drivers attended. Meeting attendees testified that two Union agents, Rene Torres and David Acosta, stated:
1. Honeyville is run by Mormons;
2. Honeyville is giving its money to the Mormon Church;
3. Companies have tax incentive to give profits to churches, which should be shared with the workers instead;
4. Honeyville’s Mormon owners not only give their money to the Mormon Church, but they also give money to the Mormon missionaries; and
5. Mormons are missionaries, and missionaries speak good Spanish.
Rec. vol. Ill, at 38-39, 75-76, 149-151, 155-56, 174-76, 298-304, 308. Mr. Torres is a driver with Honeyville Grain, and Mr. [1272]*1272Acosta is a business agent and organizer for the Teamsters Local 396. Mr. Acosta claimed that he made no reference to missionaries or the Mormon Church at the meeting.
The most extensive testimony came from Enrique Erazo, a Honeyville driver who attended the meeting where the religious remarks were made. At a Board hearing, Mr. Erazo testified that Mr. Torres stated:
[The drivers] have rights to benefits. So, the money the Company was making — -was a rich Company and so, the money that the Company was making, they needed to share it with every worker and improve the benefits to workers.
Since the Company was a Company run by Mormons, [the Union] said they would ... see to it that they would make better contributions — they did to the church and they would also distribute or share that money with Missionaries going out of the country and because the money was tax deductible and that is why they would give part of that money to the Mormon Church, instead of giving it to — -sharing it with the workers — the opportunity that they have in order to better their way of life.
Id. at 38-39.
Mr. Erazo further testified that the meeting attendees applauded after Mr. Torres discussed the distribution of the company’s profits and referenced the religious beliefs of its owners. Neither party has put forward any evidence about the religious makeup' of the unit employees. The religious remarks were made at one of about ten Union meetings held prior to the election. -
A Regional Director of the Board investigated Honeyville’s objections to the election and directed that a hearing be conducted as to nine of the objections. After the hearing, the Hearing Officer recommended that the Board overrule each of Honeyville’s objections, including the objection about the religious remarks, and certify the Union. The Hearing Officer’s Report stated:
[Wjithin the context of the April 7th Union meeting, Acosta and Torres were agents of the Union to the extent that their statements were made to all the unit employees in the presence of Stephenson [the Union’s business agent] and to the extent to which Stephenson failed to repudiate their statements. Nonetheless, here, [Honeyville] has not met its burden to show any religious comments were inflammatory in nature. In the context of trying to persuade the unit employees that they should improve their lot, the evidence supports that Torres stated to unit employees that if an organization contributes to a church, then that organization has less profits to share with its workers. He also said that companies have business incentives to reduce their taxes. Within the context of his statement reasonable inferences can be made that Torres was talking about Honeyville and the Mormon Church.
Nonetheless, whether or not Torres’s comments are true, the comments are not prejudicial to the extent that the employees would not be able to weigh .the truth of the matter to reach their own conclusions. [Honeyville] put forth hearsay (or at least non-probative) evidence that many of the managers at Honeyville are Mormons, yet [Honey-ville] did not put forth any evidence of the religions of the unit employees or any evidence concerning why the statements as alleged specifically appealed to religious prejudices that the unit employees may have had. Additionally, the statement that missionaries speak better Spanish than non-missionaries is equally lacking in inflammatory value, and [Honeyville] has failed to show how and/or if [1273]*1273the statements would inhibit the employees in their ability to make an informed decision about how to vote and/or how to evaluate the comments of Torres.
Furthermore, even if hypothetically, [Honeyville] had made a prima facie case that the statements were inflammatory, the Union witnesses have provided sufficient context to all the statements to show a non-inflammatory purpose for each and all of the statements.
Rec. vol. V, doc. 15, at 18 (Hearing Officer’s Report and Recommendations, dated July 18, 2002) (hereinafter “Recommendations”).
The Board adopted the Recommendations and certified the Union as the exclusive collective-bargaining representative for Honeyville’s drivers at Rancho Cucamonga. See id., doc. 18, at 8 (Decision and Certification of Representative, dated Feb. 6, 2004) (hereinafter “Certification”).
After the Certification, Honeyville refused to bargain with the Union. The Union filed charges with the Board. The Board’s General Counsel then issued a complaint alleging that Honeyville had refused to bargain collectively with the Union, in violation of sections 8(a)(1) and (5) of the National Labor Relations Act (“the Act”). See 29 U.S.C. § 158(a)(1) and (5). Honeyville filed an answer, reasserting its objections to the Certification, and the General Counsel subsequently filed for summary judgment. The Board granted the motion for summary judgment. Rec. vol. V, doc. 29 (Decision and Order, dated July 30, 2004). The Board concluded that Honeyville violated the Act by its admitted refusal to bargain with the Union, and it ordered Honeyville to cease and desist from interfering, restraining, or coercing employees in the exercise of their rights under the Act. See 29 U.S.C. § 157. The Board also required Honeyville to bargain on request with the Union as the exclusive representative of the drivers.
In response, Honeyville now petitions for review of the Board’s Decision and Order, requesting that we set aside the election. The Board cross-appeals to enforce the Decision and Order. This court can review the Board’s actions for the limited purpose of deciding whether to “enforcfe], modify[ ], or set[ ] aside in whole or in part the order of the Board.” Id. § 159(d).
II. STANDARD OF REVIEW
We review the Board’s refusal to set aside an election for an abuse of discretion. NLRB v. DPM of Kan., Inc., 744 F.2d 83, 85-86 (10th Cir.1984). This court reviews de novo the Board’s conclusions of law. Double Eagle Hotel & Casino v. NLRB, 414 F.3d 1249, 1253 (10th Cir.2005). “We will grant enforcement of an NLRB order when the agency has correctly applied the law and its findings are supported by substantial evidence in the record as a whole.” NLRB v. Interstate Builders, Inc., 351 F.3d 1020, 1027 (10th Cir.2003); see 29 U.S.C. § 160(e) (“The findings of the Board with respect to questions of fact if supported by substantial evidence on the record considered as a whole shall be conclusive.”). The substantial-evidence test requires only “the degree [of evidence] that could satisfy a reasonable factfinder. Furthermore, if the Board has made a plausible inference from the evidence, we may not overturn its findings, although if deciding the case de novo we might have made contrary findings.” Webco Indus., Inc. v. NLRB, 217 F.3d 1306, 1311 (10th Cir.2000) (internal citation and quotation marks omitted). “We do not re-weigh the evidence or second guess the NLRB’s factual inferences.” Velocity Express, 434 F.3d at 1201.
III. DISCUSSION
The parties agree that the seminal case describing when an appeal to racial or [1274]*1274religious prejudice warrants overturning an election is Sewell Manufacturing Co., 138 NLRB 66, 1962 WL 16079 (1982). The Board in Sewell set aside an election where a union had lost 985 to 331. Id. at 70. For four months, employers distributed anti-African-American propaganda materials focused on the union’s support for the civil rights movement, including a photo (mailed two weeks before the election) of a white union official dancing with an African-American woman, together with a story about “race mixing.” Id. at 66-68.
In Sewell, the Board described which types of racial references are allowed and which types warrant setting aside an election. It stated:
So long ... as a party limits itself to truthfully setting forth another party’s position on matters of racial interest and does not deliberately seek to overstress and exacerbate racial feelings by irrelevant, inflammatory appeals, we shall not set aside an election on this ground. However, the burden will be on the party maldng use of a racial message to establish that it was truthful and germane, and where there is doubt as to whether the total conduct of such party is within the described bounds, the doubt will be resolved against him.
Id. at 71-72. Appeals to racial or religious prejudices constitute grounds for setting aside election results if “the challenged propaganda has lowered the standards of campaigning to the point where it may be said that the uninhibited desires of the employees cannot be determined in an election.” Id. at 70-71 (emphasis added). As discussed below, a party challenging an election bears the preliminary burden to prove that the remarks at issue were inflammatory or formed the theme of the campaign. If this burden is met, the party who allegedly made the remarks then must prove that they were germane.
Here, the Hearing Officer and the Board concluded that Honeyville bore an initial burden to prove that the remarks were inflammatory, but did not satisfy it. The Hearing Officer found that Honeyville “has not met its burden to show any religious comments that were inflammatory in nature.” Recommendations at 18. The Board similarly concluded that Honeyville had not met this initial burden: “[E]ven if [Honeyville’s] evidence were fully credited, [Honeyville] has failed to demonstrate that the [Union’s] conduct amounted to a sustained inflammatory appeal or a systematic attempt to inject religious issues into the campaign.” Certification at 8 (internal quotation marks omitted).
A. The challenging party must first show that the remarks were inflammatory.
We must initially determine if the Hearing Officer and Board correctly interpreted Sewell to place the preliminary burden of persuasion on Honeyville to demonstrate that the religious remarks were inflammatory or the core of the Union’s campaign. This is an issue of first impression in our circuit. Honeyville asks us to adopt a per se rule that, in a representative election, the party making use of the religious message bears the initial burden to show that the message was germane to the issue; if that party cannot do so, the election should be set aside. Honeyville also maintains that a party making religious comments has the separate burden to prove the comments were not inflammatory. The company, however, cites no Board or appellate decision adopting such a rule, and likewise, we have found no authority for the proposition.
Instead, courts have followed a general burden-shifting regime that the Board described in its Certification, and we adopt such an approach here. Sewell and the appellate courts interpreting that [1275]*1275decision require a party challenging a representative election first to demonstrate that the religious remarks were inflammatory or formed the core of the campaign. If this burden is satisfied, the burden then shifts to the party making the remarks to prove that such comments were “truthful and germane,” as Sewell explains. 138 NLRB at 72. Remarks not found to be inflammatory or the core or theme of the campaign are reviewed under standards applied to other types of misrepresentations. See DPM of Kan., 744 F.2d at 86 (“adopting] the rule that elections will not be set aside because of misleading campaign statements, absent the use of forged documents or the alteration of an official Board document in a manner suggesting that the Board favors one of the parties”).
This framework accords with other circuits that have explicitly discussed a party’s initial burden when challenging preelection racial and religious remarks. See, e.g., Case Farms of N.C., Inc. v. NLRB, 128 F.3d 841, 845 (4th Cir.1997) (“The Board has made clear in the cases following Setuell that appeals to race or ethnicity must be ‘inflammatory’ in order to violate the Sewell standard.”); KI (USA) Corp. v. NLRB, 35 F.3d 256, 260 (6th Cir.1994) (“When a party ... establishes a prima facie case [of] an ‘inflammatory appeal’ to racial feelings, ... then the burden shifts to the party using the racial appeal to show that its remarks were ‘truthful and germane.’ ”) (quoting Sewell, 138 NLRB at 71-72); NLRB v. Silverman’s Men’s Wear, Inc., 656 F.2d 53, 58 (3d Cir.1981) (concluding that “the burden of establishing the legitimacy of the remark shifted to the Union” after determining the remark “falls within the Sewell definition” of being inflammatory); Peerless of Am., Inc. v. NLRB, 576 F.2d 119, 125 (7th Cir.1978) (“If ... racial or sexual remarks are injected into an election campaign but do not form the core or theme of the campaign as they did in Seivell, and if the remarks are not inflammatory, they should be reviewed under the standards applied to other types of misrepresentation.”), overruled on other grounds by Mosey Mfg. Co. v. NLRB, 701 F.2d 610 (1983); NLRB v. Sumter Plywood Corp., 535 F.2d 917, 925 (5th Cir.1976) (stating that “the reversal of burden of persuasion [from the party challenging the election to the party who made the remarks] occurs if the racial remarks form the core or theme of the campaign, or if the statements are racially inflammatory”) (internal quotation marks omitted).
Having determined that the Board correctly placed the preliminary burden of proof on Honeyville, we examine whether the Board had substantial evidence to conclude that the religious remarks were not inflammatory or the theme of the Union’s campaign.
B. Substantial evidence supported the Board’s findings that the remarks were not inflammatory or the theme of the campaign.
In Sewell, the Board was concerned with a party’s “deliberate” attempt to “overstress and exacerbate racial feelings by irrelevant, inflammatory appeals,” 138 NLRB at 72, but it did not define what constituted “inflammatory appeals.” The Board did make it clear, however, that it works to conduct elections free from “elements which prevent or impede a reasoned choice,” id. at 70, and it will not “tolerate as ‘electoral propaganda’ appeals or arguments which can have no purpose except to inflame the racial feelings of voters in [an] election,” id. at 71. Furthermore, the Seventh Circuit has explained that “[a] statement is racially inflammatory on its face if it is intended to produce or exploit strong racial prejudice, and is in fact likely to produce or exploit such racial prejudice.” State Bank of India v. NLRB, 808 F.2d 526, 541 (7th Cir.1986). These princi[1276]*1276pies described by the Board and the Seventh Circuit apply similarly to inflammatory religious comments.
With this advice in mind, we look at the Board’s findings about the Union’s religious remarks:
The Board in Sewell distinguished between sustained, deliberate, calculated appeals to racial prejudice (as in that case) and isolated, casual remarks appealing to prejudice. 138 NLRB at 70-72. Accordingly, since Sewell, the Board has consistently refused to overturn elections on the basis of comments with racial or religious overtones, even when they were inaccurate or gratuitous, when the comments were not inflammatory or part of a sustained, persistent attempt to appeal to the racial or religious prejudices of eligible voters.1 Relevant to the inquiry are the context in which the statements are made, and the “total conduct” of the person making the comments. [M] at 72.
Applying these principles, we adopt the hearing officer’s conclusion that the [Union’s] conduct here did not so lower the standards of campaigning that the uninhibited desires of the employees could not be determined in an election. We find that, even if the evidence were fully credited, [Honeyville] has failed to demonstrate that the [Union’s] conduct amounted to a “sustained inflammatory appeal” or a “systematic attempt to inject religious issues into the campaign.”
Considering both the context and the [Union’s] total conduct, we find that the [Union] did not overstress or exacerbate religious prejudice. The comments at issue were made at only one of about 10 union meetings. [Honeyville] offered no evidence that there was any other injection of religious comment into the campaign (through literature or other [1277]*1277means); thus, religion was neither the core nor the theme of the campaign. Nor did [Honeyville] offer any evidence showing a history of preelection tension. Any appeal to religious prejudice — if, indeed, there was such an appeal — certainly does not appear to have been a deliberate and calculated attempt to so inflame religious prejudice that the employees would vote against [Honeyville] on religious grounds alone. In any event, we find that the [Union’s] remarks would not have the “likely effect” of “preventing] or impeding]” employees from making a “reasoned choice” in the election. [Id] at 70.
In sum, because [Honeyville] failed to demonstrate that the [Union], through its preelection conduct, overstressed and exacerbated racial or religious feelings through a deliberate appeal to prejudice, its [objection] does not provide a basis for setting aside the election.
Certification at 6-8 (footnotes and certain citations omitted).
At the outset of our review, let us be clear: the Union agents’ references to the religious belief of Honeyville’s owners at this meeting were wholly inappropriate for any representative campaign, and in no way do we condone such remarks. Religious prejudice can work in subtle ways. We are particularly troubled by the testimony that the employees applauded after the Union representative’s discussion of Honeyville’s profits and incentives to contribute to the Mormon Church.
But we must also keep in mind that our ease law accords considerable deference to the Board’s factual findings, and our review here — of whether substantial evidence supports those findings—is “a narrow one.” Webco Indus., 217 F.3d at 1311. “The ‘substantial evidence’ test itself already gives the agency the benefit of the doubt, since it requires not the degree of evidence which satisfies the court that the requisite fact exists, but merely the degree that could satisfy a reasonable factfinder.” Allentown Mack Sales & Serv., Inc. v. NLRB, 522 U.S. 359, 377, 118 S.Ct. 818, 139 L.Ed.2d 797 (1998). Also, we must examine the allegedly inflammatory appeal in the context of the “totality of circumstances surrounding [the Union’s] remarks.” Silverman’s Men’s Wear, 656 F.2d at 60.
Based on our standard of review and the record considered as a whole, we conclude that substantial evidence supported the Board’s findings that the pre-election remarks were not inflammatory and did not form the core or theme of the Union’s campaign.
1. The religious remarks were not inflammatory.
Perhaps most importantly, the Union’s religious comments did not explicitly disparage Mormons or reference the owners’ religion in an overtly abusive or gratuitous manner. The remarks also did not employ vulgarity or profanity to signal that Honeyville’s owners deserved particular disdain. Cf. YKK (U.S.A.) Inc., 269 NLRB 82, 84 (1984) (setting aside an election because of a union’s repeated references to the company’s owners as “Japs” and “damn Japs,” together with printed materials stating “Remember Pearl Harbor,” “Japs Go Home,” “Japs speak with forked tongue,” and “slant eyes”); Schneider Mills, Inc. v. NLRB, 390 F.2d 375, 377, 379-80 (4th Cir.1968) (finding inflammatory a union handbill, alleging that the company president wanted to burn to death two female union employees and further comparing the president’s “filth” to Hitler). We can therefore distinguish the facts here from Silverman’s Men’s Wear, a Third Circuit case on which Honeyville primarily relies.
In Silverman’s, a union officer allegedly called the company’s vice-president a “stin[1278]*1278gy Jew” at a meeting attended by twenty of the fifty-six employees, six days before the election. 656 F.2d at 55. The court found “no reason for the remark except to inflame and incite religious or racial tensions,” id. at 58, and labeled the one-time comment as a “bald, bigoted slur,” id. at 59 n. 10. The Third Circuit concluded that the alleged remark “[fell] within the Sewell definition” of being inflammatory “because of its sensitive nature,” even though the alleged remark was not repeated. Id. at 58. The court remanded the case for a hearing to determine if the remark warranted a new election.2
The Board characterized the Union’s religious remarks here differently than the alleged “stingy Jew” comment in Silver-man’s. Pointing out the fact that Honey-ville’s owners are devout and give money to their church and its missionaries is substantively different than “the directly abusive remark alleged” in Silverman’s. Id. at 59 n. 10. Here, the Union agents sought to tie the comments to a relevant employee issue — how the company distributes its profits — and we do not believe the remarks incited religious tension in the same way as a racial or religious slur intended solely for inflammatory appeal. In short, the remarks regarding Honeyville’s allocation of financial resources did not rise to the level of an abusive religious slur. Cf. NLRB v. Katz, 701 F.2d 703, 705-08 (7th Cir.1983) (denying enforcement of a Board’s petition where a Roman Catholic priest actively supporting a union’s efforts referred to the company’s owners as Jewish, discussed the movie “Holocaust,” and stated that the Jewish owners are “getting rich while we’re getting poor,” during a union meeting at a Catholic church to a workforce comprised largely of Catholics).
Further, Honeyville has not shown how another alleged remark — that Mormons are sometimes missionaries, and missionaries speak good Spanish — appealed to the employees’ religious prejudice. As we noted earlier, neither party has described to us the religious make-up of the unit employees. We only know that at least some (and maybe all) of the drivers spoke Spanish. The union agent making that remark, Mr. Torres, denied that his two references to missionaries during the meeting had negative connotations.
Also, notably, the Third Circuit’s decision in Silverman’s was in a different procedural posture. The court there analyzed the Board’s findings to determine if the objecting party presented evidence that “raised substantial and material factual issues, so as to require a hearing.” 656 F.2d at 55. The Third Circuit concluded that the allegations met that burden and needed to be properly explored at a hearing. Here, Honeyville has already had the benefit of a hearing, and we only determine on appeal if substantial evidence supports the Board’s findings in light of the hearing testimony and the record considered as a whole.
2. The religious remarks were not a central theme of the campaign.
Finally, the isolated remarks were clearly outside of the core issues of the Union’s campaign and there was no evidence of pre-election religious tension, and Honey-ville does not dispute the Board’s findings as such. See State Bank of India, 808 F.2d at 542 (concluding that a union’s isolated racial remark — about a company’s efforts to keep depressed working conditions and low wages because most employees were of minority groups — was not “sufficiently close to the core theme of the [1279]*1279campaign”); NLRB v. Utell Int’l, Inc., 750 F.2d 177, 180 (2d Cir.1984) (holding that “typical economic issues were the essential themes of the election campaign” and the false accusations of racism were non-inflammatory). As the Board noted here, the references to Honeyville’s owners as Mormons occurred five days before the election, but at only one of about ten Union meetings organized during an extended campaign. See Arlington Hotel Co. v. NLRB, 712 F.2d 333, 338 (8th Cir.1983) (determining that a union’s one-time references to Hitler and slave ships in describing the company’s management did not have inflammatory effect and were not the campaign’s central theme).
Further, Honeyville has not shown any pre-election religious “tension” between the company and its employees that may have been exacerbated by the isolated religious remarks. Cf. NLRB v. Eurodrive, Inc., 724 F.2d 556, 559 (6th Cir.1984) (concluding that a Board hearing was warranted when a union organizer’s statement “concerning the white employees’ need for protection” was “in itself, insufficient to establish any particular intent to exacerbate racial feelings among the employees,” but the statement “placed an undue emphasis” on racial issues “in light of the preexisting racial tension that existed at the time the alleged statements were made”). The Board specifically noted the absence of “any evidence showing a history of preelection tension” in its Certification, and contrasted Honeyville’s election with campaigns involving “a history of preelection tension, [where] even an isolated reference to race or religion could constitute a sustained inflammatory appeal.” Certification at 8 & n. 5.
IV. CONCLUSION
The party challenging an election on the basis of pre-election religious comments must initially show that the remarks were either inflammatory or formed the core or theme of the campaign. Here, Honeyville did not satisfy this preliminary burden. While we in no way condone the inappropriate, unwarranted, and unjustified religious references, substantial evidence from the record considered as a whole supports the Board’s conclusion that the comments were not inflammatory or central to the Union’s campaign. “[I]f supported by substantial evidence, we must affirm the Board’s conclusions even though we might reach a different result were we reviewing the record de novo." Pub. Serv. Co. of Colo. v. NLRB, 405 F.3d 1071, 1077 (10th Cir.2005) (quotation marks omitted) (emphasis added). The Board did not abuse its discretion when it declined Honeyville’s request to set aside the election. Accordingly, we DENY Honeyville’s petition for review, and we ENFORCE the order of the Board.
