Nah, to know you are a failure you have to accept responsibility for your failings. He pathologically externalises anything negative - bad things are done to him, not by him.
Unfortunately there will always be enough people who "believe" in him in one way or another for him to be a lucrative investment for one rich asshole or other. He may lose his "legitimacy" with banks and other lenders to whom association with him could do damage, but there are enough others out there with cash and no fucks to give who will support his ongoing hubris whether that manifest in political or business/media form or other.
Aside from that I'm optimistically in agreement with your other point - hopefully some state and federal indictments will be forthcoming on other matters and one of them will stick.
