Are you familiar with the concept of limerence? It's an intense infatuation with a person typically rooted in romantic interest. It occurs when you don't really know a person, and you build an idealized version of them in your mind that likely doesn't reflect reality. You attribute all sorts of positive traits to them and overlook all their negative traits. You effectively view them through "rose colored glasses". This is how Trump's followers look at him. They have this delusional view of him as this strong man here to save them from the mean old leftists. His efforts to seize and wield extraordinary power is viewed favorably, because he is their savior. Everything he does is either awesome or it's just minimized and ignored. When he does horrible things, it's just haters looking to knock him down, because he's just giving the U.S. the tough medicine it needs. There is no way to reason with them, because you can't reason someone out of something they didn't reason themselves into in the first place. It's an emotional thing, in the same way you might be smitten by an attractive woman and build her up in your mind into something that she isn't. The only way to break the spell is when your fantasy runs into cold, hard reality. In this case, the cold, hard reality will be financial collapse of the U.S. (or worse).
