The Koch Brothers endorse Hillary Clinton. They usually support Republicans. Why're they doin it?

A lot of people are voting for Trump not because they like him, but because of how crazy he is. People are tired of the broken, stale, gridlocked US government. They're sick and fed up with no change, more of the same, constant drudgery and repetition. And some people think that voting for someone completely stupid, totally asinine and ridiculous and so far out there that it's absurd...even THAT is better than sticking with more of the same because at least it'll cause change.
