He actually does pretty well among evangelicals - he won them in the Republican primary while it was still a competitive race, astoundingly - proving that most Christians have never actually cracked open their Bibles.
He does poor, however, among upper midwest voters/people with whatever that intangible midwestern sensibility is called.
It's called being polite and respectable.
