They wouldn't want to, because it doesn't matter to them. It makes their bogeyman Trump even scarier, and keeps that desperate cash flowing to their campaign coffers so both parties can play off one another while robbing the country, and the global South, blind.
Yeah; I'm not exactly expecting that they would do anything actually good even if they did something... I suppose a small part of me is hoping that Biden being totally out of it might mean he'd do something genuinely batshit.
