Probably wrote this before, but, living in a deep blue university in a deep blue city in a light red state, I spoke to only three trump supporters. All were middle-aged white men who drove the university's vans.
Two of them had the incomprehensible logic, basically a negative stereotype. One of them said "we can't have free college, that's impossible, then we could get free school too." Another said "I'm a centrist, but the Democrats are too far left; looks like the lefties Bernie and Biden are getting the nomination. If one of the others (at that stage, it was Pete and Warren) get it, I might vote for them." I can promise you that, like with the Democrats in this thread, there is not a single thing you could have told them that would ever change their vote.
The other was maybe the most knowledgeable person about Indian politics i had ever met outside India, who would ask me questions about Modi, Naxalism, Sikhism, acid attacks, Pakistani support for the Afghan Taliban, and other such stuff at 3am. But he was absolutely a Trump supporter. For example, his takeaway from acid attacks on women was that they would be protected if India had a second amendment. And his takeaway from Pakistan was that "we shouldn't spend our money there" and praised Trump for saying the same thing, in contrast with Hillary and Bush. I once asked him about M4A and he said he's scared of NHS-style waiting times. His overall take on politics was "all frauds, this one's open about it, so I'll vote for him". Of the three, he definitely had thought through his politics, there was internal consistency and quite a lot of external knowledge, and, IMO, a good chance he wouldn't vote for Ted Cruz or Ron DeSantis.
e - someone in my phd program was a jordan peterson guy, i didnt really know him but i guess he was another trump supporter there.
e again - vans stopped after covid, no idea what their takes were on the vaccine or jan 6 or whatever.
