Double down, of course. HOW is the only question.
This isn't Bill (or even Hillary Clinton). This is A man who is a failure, a hater and VICIOUSLY angry. His closest advisers and office holding supporters are very much like him.
He is unlikely in that he in no way manner shape or form can he be posited, with respect to traditional American Culture as POTUS, and yet...there he is. He and his circle, like Adolph Hitler and his, are driven by demons. These are people whose flaws drive them AND (ultimately) destroy them. These are people who are not aware of or can't acknowledge their shortcomings or flaws. Anyone who thinks that Barak Obama is a politician who wants to survive in office and will bend with the wind to do so hasn't been watching The Insane Clown President and hasn't been reading History.
Anger is cancer of the soul. Anger destroys. Little Barak, like little Adolph, is angry.
Probably, but not absolutely, definitely so. This is why I intend to watch the SOTU. If he's at all like Clinton, he'll begin to triangulate. However, I doubt that he's enough of a politician to be able psychologically to. I suspect he'll double down and put the pedal to the metal.
