The President isn't necessarily the President. This President isn't really the President. If he tries to exercise Presidential powers, he's committing a crime. Treason, or bribery, or witness intimidation. If he tries to overrule the State Department, it's a felony. If he fires the head of the FBI, it's obstruction of justice, a cover-up, and treason. If he tweets his opinion about an obviously insubordinate employee of the executive branch, that's witness intimidation, obstruction, and collusion.
In fact, anything he does (as another FReeper observed) to defend himself in the court of public opinion is obstruction of justice and witness intimidation, by definition.
Well said.
