He’s been peeling back the onion one layer at a time, imo. He tries to backslide, after each exposure, but there’s not much left.
Two steps liberal/one step back is a sure fire way to run out of steps. I don’t doubt his mental issues are a big part of that but it’s like beer. They only magnifies who and what you really are inside when no one’s watching.
Even if his issues are under medical control, the man he is behind their mask is what he is.
