From an outsiders point of view it seems trump still has enough wriggle room to get out of this, but it really is death by a thousand cuts at this point. I can't see any scenario where the man does not implode by the end of next year.
At this point, the concern should be around making sure he doesn't take your country and maybe even parts of the wider world with him.
But no matter how much the GOP play interference, he is done. It's not even that he has used up his lives or lost the ability to shake off scandals, it's simply that he is so broken that he is starting to play defence. The problem is with that every time he tries to smooth things over he makes it worse.
He won't shut up, but if he doesn't, the evidence against him will just build faster. It's literally a death spiral at this point.
But honestly, I do not think it matters. The rabbit is out of the bag now. All the GOP need is another Trump with a bit more political skill and a tiny bit more common sense. Things are not returning back to how they were before Trump, whether he is in office or not.
