Just recognize reality. Trump has spent his life in media. He’s skilled at crafting a narrative that appeals to the dumbest 51%. His wide variety of horrible characteristics works against that, but you need a candidate who can take advantage of those horrible characteristics. Rather than doing that, Biden has played into Trump’s narratives, despite tons of time to prepare. If we would let ourselves see it, we’d recognize it’s a binary choice. Go with Biden and make Trump president, or go with anyone else and stop him.
We can say the media is being unfair to Biden, and it probably is. But it doesn’t matter. Biden is clearly terrible at getting positive coverage - whether that’s his fault or the media’s (and I think we can all recognize it’s at least partly his fault). If the goal is to stop Trump, we need someone who can get better coverage.
