Why it matters: Trump has recently taken steps to shore up his evangelical base after an editorial in Christianity Today, a magazine founded by the late Rev. Billy Graham, attacked his "gross immorality and ethical incompetence."

His latest move was an "Evangelicals for Trump" event last weekend at one of the largest Latino evangelical churches in Miami.

The state of play: In the video, the group warns evangelicals to "beware of false prophets."

"IF THIS IS THE BEST AMERICAN CHRISTIANS CAN DO," it says, "THEN GOD help us all."

The big picture: The Lincoln Project, which announced its creation last month, aims to persuade "enough disaffected conservatives, Republicans and Republican-leaning independents in swing states and districts to help ensure a victory in the Electoral College, and congressional majorities that don't enable or abet Mr. Trump's violations of the Constitution."
