A lot of people who voted for him in 2016 didn't know any better. I read about women in Pennsylvania who voted for Trump in 2016 and are now very embarrassed about their vote. They only knew of him from reality tv and thought he was a great business man. They had no idea what a crook he is or much he would fuck up the country. They are all voting for Biden this year. One voted third party because she didn't like Hillary. She also regrets that decision and is now actively trying to convince people not to vote for Trump.
Hopefully there are more people like them. Sadly, some voters are very misinformed and base their vote on personality or some other stupid thing. Trump has lost much of his support of white females, although I have no idea how any female could vote for the sick fuck, I'm at least glad to see that some are beginning to see the light. I personally knew of some third party supporters who said they didn't like Clinton so they couldn't vote for her. What the fuck does liking someone have to do with why you vote for them!
It's really sad that there are still so many people who have been fooled by a disgraceful conman. Sadder yet, there are still so many who cling to the Trump cult.
