I don’t think this is really a moderates thing, I think this is a Biden ego thing and the Democrats being paralyzed by their deference to established leaders even when they’re clearly in the wrong. The only Democrat on record saying he should step down is some nobody. And there’s a whole lot of moderates damning him with faint praise of “that’s something Joe Biden will have to decide” rather than “no, of course he should stay in”.

I don’t expect Biden to be replaced by someone not thoroughly bland and plotting a triangulating path through the electorate. Hell, it’s entirely possible Biden’s fits and starts of throwing the left a bone occasionally will be “the good times” for progressives. But what I do know is the Joe is almost certain to lose and we need someone who can win. Sub in Kamala or Buttigieg or (ugh) Newsome, it’ll still let me breath a sigh of relief.
