I obviously agree with Biden stepping down. Any man and his dog could see he wasn't fit for another term. But for the DNC to swap out a candidate this late in the campaign, the obvious angle for the GOP would surely be that if they can't even run their campaign without this happening, then how can you trust them to run a country. And while the coasts are loyal democrats, that angle could resonate with much of the middle class who are battling to pay bills etc and are worried it may get even worse.
