He knows his fans. Dumber than rocks. It isn't really clear that he is very smart, but he has the ability to convince people, some people, that he is a stable genius. He has convinced 3 women to marry him. He has convinced three other women that we know of to have sex with him. Probably dozens more. He has convinced any number of morons that they should do crime for him. And millions of deplorables to believe him. Sounds like hitler to me.
