But what if they believe in witches?

Rep Pete Sessions says D's call #Benghazi cmte "a political witch-hunt. Well, Mr. Speaker, that must mean there is a witch somewhere."

Does it?  Witches? Not Wiccans or pagans, or generally troublesome women, but, erm.

There must be witches. 

Which would explain the magical thinking?

I dunno, does Pete Sessions look like a man who believes brooms can fly? I'm sure he thinks all kinds of things can fly. Actually, I think he believes his belief is contagious. Funny old thing, witch hunts. They work whether witches exist or not. They get someone, after all.
