Apparently insane enough to not have facts matter to them. Not that Biden is much of an alternative. But Trump? That's just insane! Let's take a look at him. First, he tried to commit a coup here in the U.S. That's TREASON! He even wanted to lead the attack on the Capitol Building himself. But his Secret Service guards wouldn't let him. He also claimed that the election was stolen from him. With absolutely no proof. Biden won the election by over 7 million popular votes. You can't fake that. Also, how people vote is kept secret. But I'm pretty sure that they voted isn't. For Biden to have won to the degree that he did, apparently Trump thinks that he did it with millions of votes cast by people who either didn't exist or who had no right to vote to begin with. If that was the case, SHOW THEM! There must be many millions of them out there. Show me the list! But he can't because it never happened.
As if that all wasn't bad enough, his talk about securing the border was nothing but talk. Republicans love cheap mexican wage slaves as much as democrats. For example, I saw part of a speech given by W. Bush where he said that we should actually be thanking illegals for coming here. Also, when Trump was first running for president, he promised to deport 11 million illegals if he was elected. It didn't happen, did it. Also, Trump purposefully misled the American people about the seriousness of the coronavirus. I even saw him give an interview where he admitted to it. Apparently, the economy was more important to him than human life.
Here is another point. Trump had a sister who used to be a judge who died fairly recently. What insane Trump supporter can think that they know Trump better than his own sister. Well she herself said that her brother wasn't to be trusted. And that he had no moral standards. At least as a sister, Trump had some family loyalty to count on. But still, she said what she did. And given all of Trump's legal problems, she obviously knew what she was talking about. So all in all, if you still support Trump, you can consider yourself to be truly insane.
