What role did evangelicals play in Donald Trump's 2016 and 2020 presidential campaigns?
Executive summary
White evangelicals gave Donald Trump overwhelming backing in both elections: exit and survey data show roughly 75–81% supported him in 2016 and about 76–84% in 2020, making them a core slice of his coalition and roughly 38% of some state electorates or about 20% of the national electorate in later cycles [1] [2] [3] [4]. Campaigns treated that bloc as indispensable—Trump’s team targeted and mobilized evangelicals in 2016 and retained or increased their loyalty in 2020 through appeals to judicial appointments, abortion policy, cultural threat, and promises to “have their back” [5] [6] [2].
1. Why the numbers mattered: evangelicals as a decisive voting bloc
White evangelicals represented a large, reliably Republican segment that composed a substantial part of Trump’s coalition: exit-survey figures put Trump at about 79–81% of the white evangelical vote in 2016 and roughly 76–84% in 2020, and Brookings and Pew analyses show evangelicals made up a large portion of his electoral base [1] [2] [4]. Because they concentrated in key Midwestern and Southern states, mobilization of evangelical voters could swing tight Electoral College margins, which the campaigns recognized and exploited [1] [5].
2. What motivated many evangelicals to back Trump
Multiple sources show evangelicals prioritized specific policy and cultural goals over personal character. Judicial appointments—promising conservative Supreme Court justices to overturn or curtail Roe-era precedents—and issues like abortion and Israel were major drivers in both cycles; many evangelicals judged outcomes (courts, policies) above personal flaws [6] [2] [7]. Analysts also point to perceived cultural threat: Trump’s posture as a defender of Christian identity against a liberal secular elite resonated with Christian nationalist currents within parts of the evangelical movement [2] [8].
3. Leadership endorsements, councils and pastoral persuasion
Trump cultivated formal and informal evangelical support: faith advisory councils, prominent pastors’ endorsements, and public signaling that he would protect religious conservatives helped legitimate him inside conservative churches despite behavioral tensions with traditional Christian norms [9] [6]. Religious elites and campaign outreach reduced dissonance for many believers, turning electoral support into a form of political solidarity for institutional aims [9] [8].
4. Continuity and growth from 2016 to 2020
Contrary to expectations of an evangelical backlash, Pew and other analyses found no mass exodus from evangelical identity during Trump’s term; in some white cohorts, evangelical identification actually rose among Trump supporters and his share of evangelical support held steady or grew between 2016 and 2020 [10] [11]. Scholarship and exit-poll comparisons show Trump’s evangelical backing remained robust and in some measures increased in 2020 [2] [11].
5. Campaign strategy: targeting, messaging and mobilization
Scholars and polling analysts say Trump’s campaign deliberately targeted evangelicals from 2016 onward because of the structural importance of that voting bloc; both campaigns recognized that paths to 270 electoral votes ran “between the pews” in swing states [5] [1]. Messaging stressed policy wins (courts), identity protection, and direct engagement—rhetoric that made many evangelicals feel “dignified” and defended by Trump [6] [1].
6. Internal evangelical dissent and differing perspectives
Sources document internal evangelical disagreement: some clergy and believers viewed Trump as un-Christian or morally inconsistent with Christian principles, prompting criticism, independent candidacies, or later defections; other leaders framed support as pragmatic stewardship of institutional religious interests [12] [9]. Reporting notes both the public prominence of pro-Trump pastors and a minority current of unease and opposition within evangelical ranks [12] [9].
7. Limitations in the available reporting
Available sources focus largely on white evangelical Protestants (exit polls and Pew/Brookings analyses) and do not provide a granular, uniform picture across all evangelical subgroups or regions; some sources report slightly different percentages (e.g., 76% vs. 84% in 2020), reflecting variations in survey methods and definitions of “evangelical” [2] [4] [6]. The sources do not fully describe how non-white evangelicals or younger evangelicals differed in every state; available sources do not mention that level of subgroup breakdown consistently [10] [8].
8. Bottom line — political power and pragmatic loyalty
Across 2016 and 2020, the evidence shows evangelicals were not a peripheral add-on but a central, mobilized constituency whose policy priorities (courts, abortion, cultural defense) and identity politics delivered durable, high levels of support for Trump. That support was produced by targeted campaign outreach, elite pastoral endorsements, and a willingness among many evangelicals to prioritize institutional and policy gains over reservations about personal character [1] [2] [6] [5].
