I am not a Trump voter, but I am an American. I have a few Trump voters in my family, they say he is delivering on his promises, he has a plan, yeah but Biden blah blah blah.
I can't think of anything that could happen or be revealed that would change their mind, tbh. They are a different breed and are getting their information and world views from very different, dubious, sources. It doesn't matter what happens or is said, they won't waver. Fuck knows why
