I don’t think him to be clever at all. He has handlers. They tell him what to do.
Sure, but they don't all speak with one voice. Some of them are trying to pull one direction, others pull in another direction. Sometimes he listens to one advisor, sometimes he listens to another. It probably depends on how good they are at manipulating him.
They just don’t want to tank things too early
Again, you seem to think there's a plan here. It's much more likely that there's just chaos. One faction of advisors was listened to, and Trump liked them because he always liked tariffs. And a lot of the most effective advisors (i.e. the best at kissing ass) are the most deeply stupid. His main tariff adivsor, for example, was caught quoting an "expert" in his book that was just his own name with the letters re-arranged.
he is the mouthpiece for the cabal of evil idiots
And I don't think there's a cabal. There are people trying to influence him, but they don't agree with each-other, and many of them don't know what they're doing. They're near him because they're good ass-kissers, not because they're really clever.
People seem to be missing the one positive piece of news here: She's literate!
The only person who would make this mistake is someone who read "AI" in an ambiguous font. I know it's a low bar, but this means that the secretary of education is able to read.
