That’s all true of course but this is just polling data I’m referring to. It was during the Afghanistan pullout where Biden’s approval and disapproval inversed. I don’t actually think the Democrats are against the system that causes those other things, but I’m rationalizing the perspective of a Democrat supporter who wants to stop Trump at all costs. From that perspective you wouldn’t want Biden to run against Trump, you’d want another candidate who polls better against Trump in swing states.
