I wish somebody more politically astute than me would write about the ironic trajectory of Trump's political career. He didn't care much about politics per se -- his main goal was to be famous, great, admired, etc. Like he was always making up for that Emmy he's still mad he didn't win! And if he'd ended things on a high note, like where he was in October -- still revered or at least meekly obeyed by his party and his scary base, there'd be plenty of people who'd still consider him the worst president ever but plenty of people who would still worship him. He'd have accomplished his goals and been well regarded, at least by his own definition.
Now, instead, he's going out in disgrace, indignity, infamy. Which is why his knowing the nuclear codes is so scary. It's one way he can still get attention.
