Fascism isn't unpopular. It's very popular when people are feeling desperate.
I keep hearing people say stuff like this: He can't win! He's so fascist! He can't win, Biden did such a good job if you actually look at the facts!
That's not how elections work. People vote based on what they think will satisfy their interests, and a lot voters don't see any reason to vote for Biden, and so they'll stay home. People don't need to vote for Trump for Trump to win. They just need to give in, and Biden is a "give in" machine. He's poison to voter hope or enthusiasm, and he's going to lose if he doesn't get off the ticket.
If we want to take the threat of Trump seriously, no more hiding our heads in the sand.
