As voters head to the polls on Tuesday, Donald J. Trump’s ambitions for America’s future are almost impossible to miss. He has sworn an era of “retribution” for his enemies. Vowed to deport millions of immigrants. Fueled concerns about rising fascism.

But he is making another promise that may be overlooked, but equally transformative: He will champion his followers’ brand of Christianity across American life and government.

Publicly, the former president has avoided boasting about the main accomplishment that made him a hero to conservative Christians: ending Roe v. Wade. And he has distanced himself from Project 2025, the conservative blueprint for a Trump presidency.

Instead, his support for “my beautiful Christians,” as he calls them, leans heavily into their fears about losing power in a secularizing and pluralist country — where a majority of women support Vice President Kamala Harris.

In his final campaign events with conservative Christian activists and politicians, Mr. Trump is promising to elevate not only their policy priorities but also their ideological influence. He says he will affirm that God made only two genders, male and female. He will create a federal task force to fight anti-Christian bias. And he will give enhanced access to conservative Christian leaders, if they elect him.

“It will be directly into the Oval Office — and me,” Mr. Trump told pastors in Georgia. “We have to save religion in this country.”
