I disagree Eddie, I think there is a lot more like treason, theft of services, money laundering, fraud, mail fraud, tax evasion, obstruction and blackmail. But I do think the lying will be the smoking gun that fuels and justifies ongoing and yet to be announced investigations. And once people start turning on them, then everyone will, including his base.
If anyone remembers the movie "Can't Buy Me Love" with Patrick Dempsey. Dempsey paid the head cheerleader to pretend to date him, so he could be accepted as the cool kid. He got a huge head, she outed him, he went to pariah in a flash. Same thing here, bigger scale. Dempsey came by his money to buy fame and popularity legally. I would guess at the beginning Trump did too. He inherited and borrowed. But after those sources ran out he turned to crime to keep his charade up.
We are at that point where he is about to be outed. How well that is done depends on Mueller, and how well he does it determines how quickly Trump and his base crumble.
