Some problems: Trump has already argued that if what he does falls under official acts, it's essentially absolute immunity. Trump also tried to argue that everything he did while during his presidency, was official acts. The supreme court agreed that if something is and official act, it is protected by absolute immunity.

So my guess is that whatever Trump is doing now, he'll later argue was done as a president.

Second, should be convicted of anything, the best shot is if it's a state law violation. I'm going to bet everything I own that Trump will either pardon himself, all his cronies, and/or when the time comes, step down and have Vance pardon him. So with that all federal crimes become pardoned.

The supreme court has been very frank about this: The only, and I do mean the only mechanism is a successful impeachment. And even if Trump by some miracle is successfully impeached, we have no way of knowing how that will play out. The current supreme court majority are seemingly true believers of the unitary executive theory, so I'm guessing that with time - we'll just see Trump get more and more unchecked power. And since it's going to be done via the shadow docket, it'll likely be valid for Trump only.

I think for all intents and purposes - and I don't mean to sound defeatist when I'm saying this - people should just accept the fact that Trump will be untouchable for the rest of his life.
