That’s a good rant. But Trump is more like Mic Jagger or Michael Jackson. He’s going to have fans lined up, he’ll sign some Trump memorabilia, give a rousing speech and move on to the next event. It is unrealistic to expect him to change as president. The wall, the tariffs and the tax cuts are probably a done deal, but even those will be traded for something. Everything else will be hit or miss. Personally I don’t give a damn because the politicians and hollywood have hosed our country and we need more than Trump, we need a reset. But Trump may also help fracture the GOP which would be a very good outcome.
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.
