Without fail, every one of them has a _visceral_ negative reaction to a hypothetical Trump 2028 term. It’s stunning. This is not a “I wouldn’t vote for a felon/rapist/whatever” type of red line that falls apart when you question it - they are universally against it. I sincerely think screwing with the election terms or dates to prolong Trump’s term is likely to cause immediate and shocking support evaporation. Enough to embolden Congress to do stuff, and he won’t have enough control over any armed agency to do anything to Congress.
I think that a Trump who is trying to avoid prosecution for $crimes is much more likely to throw his weight behind a GOP candidate in early 2028. Vance or whoever. That’s his best chance to stay out of jail (for prosecutions political or legitimate, doesn’t matter). After a few solid months of propping up another GOP candidate, Trump’s base will be even less rabid about him specifically. He’s going to be old news in late 2028.
If Trump doesn’t support another candidate in 2028, then I’d start to worry. I just don’t see it happening - the game theory very obviously says he must support a not-him candidate by early 2028, and doing that will make it even harder to pull off shenanigans.
