Nevermind about the "arrogant scientific atheists". And you don't "believe" in evolution, just like you don't "believe" that Pluto exists.
You simply cannot pretend someone who ignores an established scientific theory is qualified to become the most powerful person in the world.
Actually, since he's trying to be president, I'm more concerned whether he believes in proven economic theories than evolution, gravity or Einstein's theory of relativity.
If he was applying to be a nuclear physicist, then I'd be worried.
