ARTICLE SUMMARY: The short version: President Trump called Pope Leo XIV, the first American-born pope, “weak on crime and terrible for foreign policy” after Leo condemned U.S.-Iran war threats as “truly unacceptable.” A Catholic voter backlash is now forming, and it’s coming from conservative groups that backed Trump in 2024, not from the religious left. With Catholics making up roughly 1 in 5 American voters, the political consequences could land in November 2026.
President Donald Trump attacked Pope Leo XIV by name on April 12, calling him “WEAK on Crime, and terrible for Foreign Policy” in a Truth Social post. Within 24 hours, the conservative Catholic organizations that delivered Trump 55% of Catholic votes in 2024 were publicly telling him he made a mistake.
What Started the Fight
The conflict began when Leo condemned Trump’s threat to eliminate Iranian civilization as “truly unacceptable” and urged American Catholics to contact Congress to oppose the war. Leo, born in Chicago and elected as the first American pope in May 2025, has called for peace throughout the Iran conflict without naming Trump directly.
Trump responded on Truth Social, accusing Leo of “catering to the radical left,” claiming the pope wanted Iran to have nuclear weapons (a claim Leo has never made), and writing: “If I wasn’t in the White House, Leo wouldn’t be in the Vatican.”
Leo responded on April 13, speaking to reporters aboard his flight to Algeria at the start of an 11-day Africa trip. “I have no fear of the Trump administration or speaking out loudly about the message of the Gospel,” he said. “Too many innocent people have been killed, and I believe someone must stand up and say there is a better way.”
Trump, speaking to reporters at Joint Base Andrews the same evening, did not walk anything back: “I don’t think he’s doing a very good job. He likes crime, I guess.”
The Catholic Voter Backlash Trump’s Own Allies Are Warning About
The loudest criticism is not coming from the Catholic left. It is coming from the same conservative institutions that helped elect Trump.
Archbishop Paul Coakley, president of the U.S. Conference of Catholic Bishops, said he was “disheartened” by Trump’s remarks. “Pope Leo is not his rival; nor is the Pope a politician. He is the Vicar of Christ who speaks from the truth of the Gospel,” Coakley said.
Bishop Robert Barron, who sits on Trump’s own Religious Liberty Commission, called the comments “entirely inappropriate and disrespectful” and said Trump owed Leo an apology.
Kelsey Reinhardt, president of CatholicVote, the political advocacy group that backed Trump in 2024, said the post “crossed a line of decorum that plays an important part in diplomacy.”
The Electoral Math Underneath It
Brent Buchanan, a Republican pollster at Cygnal who has tracked Catholic voters since the 2022 midterms, framed the stakes plainly: “Catholics tend to be one of the swingier groups in the country, and pretty much whatever direction Catholics go politically, the country goes politically.”
The polling showed movement before this feud began. Pew surveys show Trump’s approval among white Catholics dropped from 59% in February 2025 to 52% in January 2026. A February 2026 NBC News poll gave Pope Leo a net favorability rating of +34. In contrast, Trump was -12.
Catholics make up roughly 1 in 5 voters nationally. The states that matter most — Pennsylvania, Michigan, and Wisconsin — are the same states that determine which party controls the House and Senate after November 2026. Congressional control determines Social Security funding formulas, Medicare reimbursement rates, and every federal spending priority that affects a retirement budget. A Catholic voter backlash of 3 to 5 percent in those three states changes the math on all of it.
What the Verified Record Shows
Trump’s claim that Leo supports Iran having nuclear weapons is unverified. Leo has made no such statement, and multiple Catholic leaders have directly disputed the characterization. In a seeming escalation of the Trump-Pope Leo feud, the President also shared an AI-generated image depicting himself in biblical robes during the same news cycle, deleted it, and said it showed him “as a doctor.” He has not apologized: “There’s nothing to apologize for.”
Meanwhile, Pope Leo has not named Trump in any of his statements. His position is that the church does not evaluate foreign policy from the same framework as a government, and that someone has a duty to call for peace when civilians are being killed.
Will the Catholic Voter Backlash Persist Until the Midterms?
The 2026 midterms are seven months out. Trump’s approval among Catholic voters was already eroding before this clash. Whether it slides further depends on whether the feud continues and whether Vice President JD Vance, himself Catholic, moves to de-escalate with Vatican officials as Bishop Barron has suggested quietly. So far, Vance has defended Trump. Meanwhile, Secretary of State Marco Rubio, who is also Catholic, has said nothing publicly.
