I was wondering about this just last night:
Trump voters have been pretty resilient over his ham-handed leadership since he took office. By "resilient" I mean "blind," of course. Which proves to me they knew ahead of time he would be a disaster, but voted for him anyway because they hoped he would punish the people they don't like. And when your hatred runs that deep, even if you get punished some yourself, it might still seem worth it.
