Trump's fear is based on 'ignorance is bliss.' He's been able to 'weather' so many debacles due to others propping him up, like the GOP, wealthy Jews, his Dad, etc and so on. His innate talent is as Carnival Barker. He has no depth of understanding of almost everything. He has made it by his connections with others. I'm not trying to insult him or his followers, but he has a vocabulary of a spokesman who doesn't know anything, but can sell you on it, with highly exaggerated words and superlatives and phrases. "You're gonna win so often you're gonna get tired of winning." "You're gonna have the best healthcare anywhere." He's the prime seller of euphemism, and still his ignorance is a lot like mentally ill folks who have no filter in their brain, because they lack the necessary self-awareness, of, say, like the kinesthetic sense of your body that knows its appendages' location in space internally, without a mirror.
Another example, I wonder what Trump says of the amount of misinformation and disinformation that ceased across the Twitter network when he was taken off of Twitter? He has very little clue of the enormous power of the Presidency. And surprisingly, it's astounding he didn't do more damage than he did, because as stated, 'ignorance is bliss' and Brother Trump, well, he perhaps thought of himself as a player of a tiny local fiefdom, not at all of an entire world Empire (in decline, but still).
