I kind of understand this line of thinking, I think the voters were stupid to, but Democrats need to play the game they're actually playing, not the one they think they ought to be. There were plenty of people voting against the Biden administration, the fact that Harris nearly won makes it pretty obvious that breaking off from him would have delivered a Democratic victory. But Harris stuck with Biden, so she got punished. Hate the game, hate the player, whatever, but if you actually wanna win, you gotta do what you gotta do.
