Nah, the guy isn’t dumb, he just has zero integrity. He finds ways to reframe arguments to win arguments - that isn’t easy, the dude knows his takes are garbage. Every once in a while the mask slips

Someone like Jordan Peterson on the other hand? The dude believes what he’s saying, his takes are also trash, but he’s so dogmatic in his world view that he can’t grasp anything outside them. He’s not really that dumb either, he just has issues.

If you want just straight up dumb, Trump is the epitome. He doesn’t understand anything - he just has so much charisma it doesn’t matter. Try reading his speeches - you might listen to them and think “wtf is he on about?”, but without his delivery, it’s just incoherent rambling

For an example of an idiot who can sound smart, Elon musk comes to mind. He memorizes facts the way a child does about the specs of their model cars, but he can’t apply any of that knowledge
