Well, respond the Trumpian conservatives, our vote is just the opener. We will call our leaders’ moves as we see them — the good and the bad.

Except they don’t. They might take issue with this or that White House policy. But they rarely if ever call out the president’s moral degradations. And such criticism is the only kind that truly irritates Mr. Trump.

That’s precisely why the likes of the Rev. Jerry Falwell Jr. shy away from it — even to the point of contorting themselves to defend Mr. Trump’s unconscionable response to white-nationalist violence in Charlottesville, Va. Idolatry of class, nation, race and leader is a constant temptation for people of faith, and too many are succumbing to it today.
