Look at his ilk throughout history and at this present moment. They cling to power. They can't cut their losses. He is lucky he in a country where you're pretty much bulletproof as a federal official at this level. If he were Peruvian he'd end up in jail, if he were in Thailand the military would come for him and in some parts of the world he'd end up getting hanged maybe.

He will cling to this presidency to its dying breath. The longer he stays in office, the more he can skim off the top and the more his anti-regulatory agenda can cement itself. It's also very much an ego thing. He hates the logistics of being president but he won't give them up because he can, and does, say I'm the fucking president and you're fucking not to anyone he feels like putting down.
