Trump's problem is that he doesn't care about the Constitution and the Rule of Law. All the commentary about his egotistical personality and rude behavior is irrelevant. Trump's main problem is he is basically a corrupt thug who consistently put his own interests above that of our Republic's interests. Trump supporters either don't understand this, due to a lack of civics education, lack of basic legal training, and a lack of leadership training, and a lack socialization in those fields, which are things that the upper middle class and upper class are usually inculcated with, AND/OR Trump supporters just don't care about the ideas that form the basis of our Republic (they may be authoritarians who do not care about the ideas necessary to make modern liberal democracies work). A person can also acquire this knowledge through experience. For instance, there are 3,000+ counties in the U.S., each county needs a variety of individuals to help govern it. And everyone who helps make government function, at any level, usually learns about how to do things right. They learn about the law. They learn about ethics in government. And so on.
I have become painfully aware over the years that Trump supporters have zero understanding of proper ethical behavior within government. They have no idea that many of the things Trump has done are things that should never be done at any level of government. And I think that mostly results from a sheer lack of knowledge and/or experience about how government works. I write or say, "Well, it's not okay to steer government contracts to your friends because that money is taxpayer money and it's your responsibility to make sure the office you're responsible for spends money in a responsible way..." And they say, "LOL SO WHAT HAHAHAH STUPID LIB!!! HAHAH ROFL LOL MAGA! TDS TDS TDS! Where's muh BEER?!?! LETS GO BRANDON HAHAHAHAHAHAHAHA"
