IMHO regardless the religion, you have to be a self righteous Jackass to be a never Trumper.
Just saw an ad from “Republican Voters against Trump” while watching Fox & Friends this morning. Until the end it isn’t clear if it is for or against Trump—they have clips of Reagan speaking and various images (you can kind of guess from what they selected—one of Roger Stone, one of Trump holding up a Bible at the church near the White House). It’s only at the end that they identify themselves. I suspect it is funded mainly by Democrats but has a few people who have voted for a Republican at least once in their lives. For the images to create negative feelings towards Trump, you have to have gotten your information about those people or incidents only from the mainstream media.
