I don’t have a link to it, but I did see a picture from the rally showing it, and the best way I can describe it is that he looked like that guy Mike Tyson took a bite out of. There was a decent chunk of cartilage that got blasted out of the upper and outer edge of his ear, maybe about an inch across at the widest part.
Correction: He lost big time because of mail-in votes. Trump in 2020 got the record high for votes for a Republican candidate at something like 67.2 million, which was just about a million votes less than what Obama got during his first election (which was a record-breaking turnout). Biden got around 80 million votes in 2020, breaking every voter turnout record ever.
Swing voters are still crucial because that’s how Hillary lost despite having only 100,000 less votes than Obama did in his second election, but I feel like swing voters have probably more or less already made up their minds. If you don’t see Trump for what he is already, the odds of his reaction here being the final straw seems unlikely. I think if people had better access to voting, we’d easily see a repeat of 2020 even if we were to vote right this minute.
