Which is why I've been calling him the organ grinders monkey. Trump, on his own, is neither smart enough nor skilled enough, nor motivated enough to successfully campaign for president, or successfully fill the office. There is a dude somewhere behind the camera that is helping him to do all this: he's the guy who wants the power and trump WAS the perfect stooge for it. Name recognition, already attempted politics and many, many elements to his life and personality that him completely controllable and exploitable.
But between the crimes which cannot be hidden anymore, and the dementia that cannot be ignored: trump is no longer capable of being even a puppet ruler. For this use case, that fat, spray tanned sack of jive was literally 1 in a billion. The next trumpian who will try to replace him will be missing that certain something, and won't be able to build or hold onto the cult, or they'll be smart enough to know their being played and chaff under the others control, or ambitious enough that being a puppet dictator isn't enough, and they'll out the actual brains of the operation for nothing more than spite and collapse the whole thing.
Will there be another attempted coup in the US. Sure: long enough time lines and all that. Will it be because of these conditions? No, it won't happen like this again, at least not in our lifetimes. Trump is done (so long as you all go out and ******* VOTE!) and there's no one out there that can reclaim the cult from him. At least not enough of it at any one time to matter.
