I mean, personally, I think its ok to be upset with Biden over policy positions, but also ok to be a little mad at people who don't vote because they don't agree with some of Biden's positions on certain things- since that is a vote for Trump, and I think we mostly all agree how much of a disaster it would be if Trump won, because of poor turnout/apathy. We should all still remember the 2016 election, or at least remember the disaster that was our country from 2017 through 2020 and know that can't happen again.
I honestly wish there was just about anyone else on the Dem ticket. Biden is too old, first and glaringly foremost, and has some policy positions I don't jibe with, sometimes at all. But all that aside, the upcoming election is still like a choice between an average reasonable person (who yes, makes mistakes), or voting for Hitler/enabling Hitler. And sadly, I don't think that's an overblown, or unreasonable analogy at all. You don't allow Hitler to win. Trump literally just wants office because he doesn't want to go to jail. He wants to claim immunity as a sitting president, and then pardon himself. And then continue the literal fascism that he inflicts.
If we all show up to the ballot again, Trump won't win. He won't have more support from what he got in 2016/2020 after all he's done (insurrection, his actions killing Roe, all the crimes, trials, etc). But he will win if we don't show up. Everyone, IMO, needs to remember this, no matter what they feel about Biden.
I'm not going to individually flame anyone who disagrees here, but I fully feel everyone needs to see/read this kind of message no matter how many times it takes. We need to show up. We can't sit on our hands hoping the courts disqualify him or something. Trump doesn't need to win those cases, he only needs delay those proceedings from concluding before the election takes place, so even if a guilty verdict comes down, he can have it reversed. Only we are going to stop him. Again. Don't forget.
