This is a strategic failure, but everything being talked about here is tactical. How do Dems deal with a candidate that voters are rapidly losing faith in due to his public appearances as a frail and increasingly not lucid old man? With where Biden is at, there were no good options after the debate. Pretend it didn't happen and stay the course, say thanks but drop him like a hot potato. Those are all shitty options with no guarantee of election success no matter how vociferously anyone here wants to argue them. There was no unity for any of the courses of action because the Dems had strategically blundered badly enough to only leave themselves with shitty choices.
The only good choice was a strategic one that would have had to be made 4 years ago: pair Joe with a rising star moderate with upside, use Joe's first term to make them look great, then let Joe hand them the reigns before any primaries this year. Instead, Joe was paired with a person who many here claim is unelectable due to their hue and gender, that person was put in the witness protection program for the last 4 years, Joe was allowed to say fuck it lets make it a twofer, and then he was allowed to have the political equivalent of a stroke on national TV. That is why we are where we are. If you need someone to blame, here are the people responsible. Your champions of democracy, the Democratic Party:
