Sometimes I think of Trump as a standup comic without jokes. He has set-ups but no punchlines.
The great comics don't memorize jokes and go out on stage and repeat them like robots. They improvise. It's a strategy. They're just talking, often in a somewhat transgressive way. Like court jesters they say things polite society keeps mum. When they get to a punchline, it seems natural.
Trump walks up to a mic and starts improvising, but what he says goes nowhere, and it has grown repetitive. He's lost in a personal fog. If he has a point, it's that he is a victim of a system that made him a billionaire. And maybe he is a kind of victim but of a family of pimps and cheaters who made sure he would never know love or friendship.
