On what planet? Evangelicals were/are about the most loyal part of his base and they were there from the beginning. Like many non believers, you sound like you don’t know what you don’t know about Christians and other faith inspired people. That typically does not slow people down on making absurd comments made up from negative stereotypes and profound ignorance. The notion that faith based people would turn on a dime at some point is weird. Their passionate involvement and support was absolutely necessary for others to get past their initial reluctance to to support a NYC playboy. I had a number of conversations with evangelicals before the election about their angst and struggle as to whether to support him. Most decided he was a good bet and most also only feel more supportive as time has gone by.
