I think a common failing of those who hate Trump, myself included, is failing to understand why Trump is in power in the first place. Not who he is, but what he is. It is easy to dismiss him as a populist demagogue riding to power on the ignorant masses, but that isn't the full truth of it.
Trump taps into something that is unbelievably ancient, powerful, and deeply human. He is the living, breathing essence of the very first political movement that ever existed, tribalism. Humans came from a group of social hunter-gatherers that formed these closely knit social groups to survive. The tribe was everything, anyone that attacked the tribe was an enemy. The tribe defines what is right, the only unforgivable sin for a leader is weakness.
Trump made people feel like a part of something bigger then themselves, a political and social uprising that would vindicate everything they believed in, even if they had never considered or codified those beliefs before. He convinced them he was their leader, their voice, he was one of them, but better then them. As long as they remain in the tribe, they won't betray him. Doubt destroys any social group, it is anathema to a tribal society.
Remember when "Deflategate" happened? Patriots fans first refused to admit any wrong doing at all, then gravitated toward putting all the blame on the ball handlers, Brady and Belichek couldn't possibly have been involved, they sacrificed the tribe member for the good of the tribe, because the leadership had to stay unquestioned. Seahawks fans believed it all at the first whispers, concocted elaborate conspiracy theories tying all rivals into a diabolical plot, because of course they couldn't question that their tribe lost because the Patriots were just better at football.
This isn't really an attack on Trump supporters either, it is far more human then most of us are comfortable in admitting, it is in all of us. If you join the Army, you will go to basic training, where they will put you into a platoon of about 60 people. These platoons are filled randomly, usually by grabbing all the privates that came in on the same bus. But over the course of the next few months, you will be taught that your platoon is better then all the other platoons, that they don't work as hard as your platoon, they are not as tough as your platoon, they just suck. The drill sergeants will lead you in chants and songs about how much the other platoons suck, and how awesome your platoon is, and you will believe it. Everything you see will reinforce it, if you see them leave the training area early, it is because they are soft, not because they got there before you. Humans need this, need to be part of a group, it is one of the strongest social urges we have, logic or reason will never shake it.
