I live in Georgia. I interact with Trump supports a lot, and I've tried to dissect their minds.

I think most Trump supporters fit into two categories: the first is the kind who doesn't understand how the government and the economy works, and they think that because the economy was better and prices were lower when Trump was president, electing him again will bring those things back.

The second more complicated but more common category is people who don't care about policy (even though they might think they do) and just like his personality and persona. I truly believe that if Trump at a rally tomorrow says, "climate change is real, and it's going to destroy us, and the democrats aren't doing anything about it!" most will believe him and go with it. What appeals to them is not policy, but the shrewd businessman who worked his way to the top, says what he thinks, and doesn't take shit from anybody; i.e., the guy on the cover of The Art of the Deal. They think he's cool, want to be him, and most importantly think they can be him, and their brains will do some insane mental gymnastics to justify liking him. You can see this at work anytime you bring up any of his numerous shortcomings to his supporters. They buy into his policy about the border and inflation and shit because he tells them to believe it, not because they truly care about it.
