I found that very revealing of some of the factors I've always thought are at play for Trumpists. So many of these people just don't know how the world works.
There is a certain type of stupidity (I don't mean that to be harsh, but I can't think of another term) in which people seem unable to make associations at a conceptual level. They can react to immediate events, they can be trained to do rote tasks, they can read and write, but there's a layer above that is simply missing. This limits their ability to make sense of the world beyond their immediate direct experience.
That ignorance of how things fit together makes the world seem even more dangerous, threatening and chaotic than it is; "bad things" happen to them or people they know and they can't really explain it. This generates considerable anxiety or fear, which in turn makes them vulnerable to conspiracy theories and misinformation: they have no context in which to properly evaluate information. And it's what makes them so vulnerable to authoritarian figures who provide simple solutions.
So here you have people who are provided a ridiculous, inaccurate view of what is happening in their government, who storm the capitol with almost a child's expectation of what they can do about it, and with no self-awareness about how their actions will be perceived by other people. At some level, they are incredibly simple-minded.
