Trump himself exemplifies that. Trump is not an idea guy, he is not particularly bright, and he's got a massive ego. This is all stuff even some of his friends admit, before he was even president. I get that most Trump supporters aren't blithering retards, but just look at a lot of the stuff the Trump wing has done... QAnon, the Capitol riot, cringe "meme magic." What did Trump really get done while in office, on his big promises? He barely has a handle on modern culture and current events, is basically just briefed on things by his aides, and his opinions change depending on who he is trying to impress and what the last person who spoke to him said to him.
I'd be surprised if Trump has even read a book in his life. Trump was all about soundbites and his biggest fans were just okay with that.
Then there's Trump's horrible handling of the culture war shit. Trump truly did not really understand what was going on. He wasn't some warrior against political correctness, he barely understood where it was coming from. The worst thing about Trump was that we had a true maverick in the White House and he wasted a lot of it by being self-obsessed and completely ignorant. Trump's fans liked to imagine Trump was something he wasn't. He was never going to be a serious contender against political correctness since he has no understanding of civics, the constitution, and history. Trump is undereducated, vapid, and and impulsive. Trump wasn't even that warm to the second amendment. Blustering and snark is not real political work. Just look at AOC.
And I voted for Trump the first time around, didn't vote the prior election.
Or do you still think everything going on now is Trump's 4D chess? Ridiculous that his biggest fans insisted he was some amazing puppetmaster. Guy very clearly does not understand a lot of things. Trump is not an intelligent person, he's actually fairly stupid. The fact that he revealed just how stupid everyone else is merely by not being part of the machine or woke doesn't mean he had substance.
