Trump is old and is not the leading example of a healthy person. I think there's an entirely reasonable chance that nature takes care of this one for us.
That said, I don't think it matters at all. This isn't a Trump problem. Sure, he's the figurehead, but there are ample figureheads waiting in the wings, just as malleable to the alt-reich's needs. They will be more than happy to step in and allow the current dismantling of the USA to continue, and for Something Very Else to be built in its place.
Yup, exactly. Hell, even if Trump were to die of a heart attack tomorrow, Vance would happily continue the cureent trajectory, and he might even be better at doing so.
The cult of personality would die though, with a considerable impact to the regime. We've been predicting the death of orange man for years considering his diet, and yes it's a miracle he's lived this long, but an often understated asset of his is that he doesn't drink an once of alcohol. That can help him survive way past his 2nd term, I think.
