If he didn't self-destruct and instigate a literal insurrection attempt at the capital, I would have said he'd continue to fleece his supporters dry of money and weasel his way into his own media channel. Now, I fully expect Trumpism to return to it's natural state (Republicans will act like their reactionary populists are fringe) and in a couple years time Republicans will pretend that they never supported him at all. Trump will be locked in legal battles and Republicans will insist we just get over it and move on because "unity."
