How quickly will Vance and the cabinet 25th amendment Trump and boot him out? It’s not like it’d be hard to make the case he’s mentally unfit it they chose to go all in.
That raises the question: how deeply psychotic would Trump's statements have to be, to trigger the 25th? He's telling his rally crowds this week that American kids come home from school having been put through gender reassignment surgery -- without the parents' consent. This is barking mad, but he's still their boy. (And he's already in diapers, remember.)
I can't think of many scenarios that would convince his base that he's lost it. Maybe if he came out on stage and said, "What the hell is wrong with this country? We've got to get back to the pre-Reagan marginal tax rates, folks. Otherwise we'll never climb out of debt. And we've got to reinstate all the sections of the 1965 Voting Rights Act, because, as many people are saying, we need everyone to have a voice. And it's madness to sell combat weapons as collector's items, folks. Madness."
That, I think, would get him institutionalized.
