Some of those dipshits wore hats or shirts bragging about voting for a felon. Not because they really thought crime was ok in general, but because they were willing to turn a blind eye to it for him. That it was better him, a felon, than a woman. Her. A Democrat. All the things he is, at least he's not one of them.

It's pure brainwashing, cultish groupthink, animosity, dehumanizing othering. They're not just morons, they're goddamned hateful, and they revel in it.
