There is a high correlation between religious belief and conservatism. Conservatism in the U.S. will not survive if Christianity doesn’t. That wasn’t the point of my argument anyway.
The point was that I get the impression that Trump is not exactly comfortable with the religious right. Even if it is justified, it puts him in a position of having to be insincere since within the Republican party it forms the largest single constituency.
I’ve heard Trump mention God in many speeches.
