There's a bit of the narcissist in all of them. They can't admit to having made a mistake, even if it was an honest one. They're too smart to be taken in by a con artist. It's the same with a great deal of what they've internalized as "truth".
You're the second person that told me that today. I disagree.
They LIKE Donald Trump and all that he stands for. They are crass, classless and have no regard for the law or democracy. They've been spoon fed the idea that winning at all costs is always acceptable when it comes to politics. They'll cheer for Mitch McConnell stonewalling a Supreme Court nomination but will start hyperventilating when Congress dares to challenge Trump.
Their hypocrisy has no limits. Like Trump, they have no shame and are driven by narcissistic attitudes towards people that are different. Also, you can't discount that many of them are easily manipulated and tend to believe in wild conspiracy theories that have no basis in fact. When presented with facts, they discount them as conspiracies. Many of them have difficulty spelling and forming sentences. I don't think a majority of Trump supporters are worried about being proven wrong. I think they have idealized the sociopath and will go down in to the pits of hell with him if they had to.
Watching this unfold in America makes it easier to understand how Germany allowed the Third Reich to take hold.
