Morning thoughts

I was just thinking about this this morning--not that I don't think about this on many mornings. There are a lot of books out about trump and his administration and his many flaws ("flaws" is far too gentle a word...). I am very interested in what motivates his followers--there are no books on that subject, are there? Lots and lots of articles to be found trying to explain it, but no book that I know of. What made them like that? It's too easy to say "They like him because he is them." Is it fear that drives them? Hate? Why? At some point all of us encountered that moment when we decided which way to break--for trump or against him. What made us say no way and them say he's my guy? I would really, really like to understand the psychology and origin of their leanings. Bad childhood? Bullied a lot? Abandoned?
