The coalition that delivered Donald Trump two presidential victories is showing stress fractures that no amount of Supreme Court appointments can repair.
A Reuters/Ipsos poll released this week finds white evangelical Christians—long the most reliable Republican voting bloc—divided almost evenly on the administration's military campaign against Iran and its intensified immigration enforcement. Among self-identified evangelicals, 47 percent support the Iran intervention while 41 percent oppose it, a startling split for a community that has historically rallied behind Republican foreign policy with near-unanimity. On immigration raids targeting families, the numbers are even tighter: 44 percent approve, 45 percent disapprove.
The theology of fracture
The divide maps onto a generational and theological rift that has been building for years but is now impossible to ignore. Older evangelicals, particularly those aligned with prosperity gospel and Christian nationalist movements, remain firmly in Trump's corner, viewing the Iran campaign as a necessary defense of Israel and the immigration crackdown as biblical enforcement of lawful borders. But younger evangelicals and those from Reformed or mainline-adjacent traditions are breaking ranks, citing Just War doctrine, the parable of the Good Samaritan, and what one prominent pastor called "the moral incoherence of bombing Iranians while claiming to be pro-life."
The Southern Baptist Convention's annual meeting last week saw unusually pointed debate over a resolution on military ethics, with delegates ultimately passing a watered-down version that pleased neither faction. Russell Moore's departure from the SBC in 2021 now looks less like an aberration than a harbinger.
The electoral math
For Republican strategists eyeing the 2026 midterms, the poll is a flashing warning light. White evangelicals constitute roughly 25 percent of the electorate and have voted Republican by margins exceeding 75 percent in recent cycles. Even modest erosion—say, a shift to 65 percent Republican support—could flip competitive House districts in Georgia, North Carolina, and Arizona. The administration's calculation appears to be that evangelical voters have nowhere else to go, but the poll suggests a meaningful share may simply stay home.
Democrats, for their part, are unlikely to capture many evangelical votes directly, but they are already targeting their messaging at evangelical women in suburban districts, emphasizing family separation at the border and civilian casualties in Iran.
Our take
The evangelical movement sold its political soul for judges and got them. Now it is discovering that transactional politics cuts both ways. When your coalition is held together by Supreme Court seats rather than shared conviction, policy disagreements that would be manageable in a values-based movement become existential. Trump may still command evangelical loyalty in 2026, but he will be leading a congregation that no longer agrees on what it believes.
