I have a book somewhere on presidential personality profiles. Most have been, in the Myers-Briggs schema, Guardian-type personalities (best example: Dubya). The worst ones, like Slick and Barky and FDR, have been opposite types, what they call Artisan (Arty-Farty for short), performance-type personalities to whom "all the world's a play" .... and they don't necessarily feel any obligations or responsibility for outcomes. It's all about the limelight and showing their good side, to them.
I'm afraid Trump's the latter -- you can metasearch the personality type sorters, two of the most useful are found in The Color Book and Myers-Briggs, and another is the Disc Profiler (DISC is an acronym).
Point is, with these personality sorters, if you profile a guy, then believe what you read! What you see is what you get. If you don't know, you can use questionnaires about what you know of Trump's personality (including the private side we don't usu. discuss, some of which is encouraging) to sort him out. But if he's an artisan type, that "all about me" stuff won't go away, no matter how disgusted with it we might be after eight interminable years of Obaminate destruction of society and the Republic.
I am afraid the destruction of society and the Republic will continue unabated. The only bright spot in that regard is that he will temporarily slow our transition to having numerous barrios seen elsewhere the world. That includes both the Hispanic barrios which I have traveled through and occasionally gone into here, and the Muslim no-go zones. Those are a form of social rot. We could also get an economic boom.
But hollywood will continue to prosper and may even do better with Trump since he has worked with them before. Social issues will be put on the back burner. The supreme court nominees will be a bit of a crap shoot although better than anything Hillary would come up with.
