The main reason, I submit, is that most of Trump’s backers are authoritarian followers—people who submit too much to the leaders they consider legiti… - Bob Altemeyer

Sometimes, when I tell people that I study authoritarian personalities, they say things like, "Oh, you mean neo-Nazis and the Klan." When these people are psychologists at conventions or the president of my university, I say "Right," because I know they will probably instantly forget whatever I reply. But I am more forthcoming with others. Most people seem surprised when I say, "No, I study normal folks, not Nazis." Few people, unless they are familiar with the history of fascism, understand that people as ordinary as you and I, and our friends and neighbors, might bring down democracy if the going got tough enough. But we are the people who, driven by fear and cuddling in our own self-righteousness, could create the wave that would lift the monsters among us to power. And once the monsters acquire the powers of the state, their evil explodes. Can one credibly talk about fascism in the North American context as we approach the year 2000? Is it even remotely possible that the horrors of Nazi Germany could someday occur in Canada or the United States? When I talk about prefascist personalities, do I seriously propose that many North Americans could act like Hitler, Himmler, Hoess, and so on? [...] although the Nazis did monsterous things, it is a mistake to thing that only ardent fascists and psychopathic killers became Nazis. Adolf Eichmann struck some as a bland person, not particularly anti-Semitic, who basically wanted to advance his career and so worked hard to impress his superiors. His evil was "banal." I can also imagine that many of those who made the arrests and transported the victims to the death camps would have been described as "good, decent people" by their families and neighbors. So would many of those who ran the slave labor camps in which hundreds of thousands of prisoners perished and maybe even the SS soldiers who massacred whole villages. You can be an ordinary Joe, or Lieutenant Calley, and still do terrible things. One of the first things Americans learned about the militias, in an Associated Press story dated April 27, 1995, is that they were "ordinary people who feel pushed."

There’s a hidden danger to authoritarian leaders in all this. When they discover their followers will believe anything they say, even things that contradict something they said earlier, they get sloppy with their lies. Maybe Donald Trump always was careless with the truth. But it seems that over the past two years he has become downright reckless. His base will swallow anything, he has learned, so he just says the first thing that comes to mind. The trouble is, for him and the future of his presidency, Truth happens. Constantly. It may be seen differently by various folks, but things did happen as they happened, not something else. You can only ignore the truth so long, and then reality will inevitably catch up with you. It will destroy you if you have been massively denying it.

Republicans fear the wrath of Trump so much because he owns the GOP base. Always ready to emphasize the obvious, I have said many times that without a crowd of ardent supporters, a wannabe dictator in a democracy is just a clown on a soap box. The crowd is now well-assembled in America. Indeed it was brought together by Republican strategists for their own ends, with only a few like Barry Goldwater anticipating the newcomers would turn the “big tent” into a tabernacle and drive out all the non-believers. Having sown the seeds of its own destruction, the GOP is now reaping the whirlwind. We understand quite well who Trump’s followers are. The October 2019 Monmouth Poll reported in Authoritarian Nightmare found they are the most prejudiced people in America. Their prejudices and many other shortcomings are rooted in authoritarianism, and studies show that authoritarian followers have many emotional and cognitive weaknesses which explain why they are longing for a strong leader who will take their side against the “others” they find threatening. They are highly fearful, ethnocentric, and have uncritically copied the ideas of the authorities in their lives. Their beliefs are highly compartmentalized, even contradictory; they use many double-standards in their judgments; they have lots of trouble distinguishing good from bad evidence; they are highly defensive and dogmatic; they have little self-insight, and a host of other imperfections. Demographically, the two pillars of Trump’s base are white Christian evangelicals and white male blue-collar workers. Both groups score highly on a measure of submission to authority named the RWA Scale.
