Joe Biden called Trump supporters garbage. He said what many people who oppose Trump were thinking, "These people are morons. They fuck their cousins, they go full sibling."
On the other side, you have Trump Supporters crying, "Everything is rigged; there are pedophiles in a popular pizza joint where those commie democrats hid Hunter BIden's laptop."
I don't care much for either candidate, but I know a lot of decent, hardworking people who will vote for Trump. On the other hand, I see many decent people who will vote for Harris. Barring the lunatics on both sides, I think most folks are voting for what they think is best for them.
The USA has always prided itself on its democratic process, and that's what it will do.
The demise of the USA is not in its politics but in its polarization and tribalism.
