Even the stupidest of fools is bound to develop a skill or two along the way
"He's the worst chess grandmaster of the lot. Never stops playing, keeps ranking up, just coasting along on the sheer number of games he's played badly and learned from. Hands down, dumb as shit, I would only lose to him 99.95% of the time."
Again, I think the term "stupid" is just a pejorative at this point. If he was a democrat who kept winning upset elections and outfoxing supposedly superior opponents, what kind of liberal would talk about him this way?
I think his stupidity is a selling point as well
He's not fixated on looking like a braniac, which means he's not getting caught in the Tucker Carlson trap of "You don't even know how many people are in Iran! How can you support bombing them?" Trump isn't claiming he's got the encyclopedia memorized. Much like Bush Jr and Reagan, he's focused on what plays well with the audience, not what sounds "smart" to the debate judges.
Is that stupid? Not when it accomplishes your intended goals.
Incidentally, one of the "dumbest" things Trump did in the wake of his '24 win was that ridiculous cryptocurrency that let him take bribes openly from foreign governments. It quickly restored him from "billionaire on paper" to "real fucking billionaire". Not because it was so insidiously clever or legalistic, but because the Biden DOJ never prosecuted him when he was out of office. What's more, the courts that Democrats refused to stack when they had a majority, have given him a free pass on criminal misconduct.
You can give a lot of credit for that to Mitch McConnell, as he spent his whole Senate career carefully staking appointed positions and encouraging career hires with Federalist Society flacks. But Trump's the guy who is going to capitalize on all McConnell's hard work and Clinton/Obama/Biden's passivity. So who really looks like the dumb-dumb here?
Per the CNN story, its certainly possible he had a mental break after failing to get a job in the forestry service and just decided to take it out on a couple of firefighters before offing himself.
Did his parents holding extremist political views and a fetish for firearms play a role in his actions? Would be more unbelievable if they didn't. But I don't think he'd have been better off with a couple of parents who were firmly in the Ted Cruz camp or disaffected Liz Cheney die-hards, either.
If I was to take a wild guess, I'd say this was the direct result of a kid who was out of high school, unemployed, with no real future on the horizon, who was terminally online in a community of (likely a large number of bot-accounts and trolls) telling him he's worthless and should just off himself.
A classic problem of "surplus males" that plague every militant reactionary society.
