My sense is that the press conference was ok, not great (a few gaffes and mixed up names). Biden made it clear he intends to be the candidate. I suspect he will be absent a catastrophic health event or if the big donor $ starts drying up (NY Times is reporting some of that today). Swing state polling looking worse for Biden but hard to know if that's a lagging reaction to the debate debacle or something more permanent. We'll see.
