Here we've been being lectured that we don't understand the stakes if we don't all line up behind Biden, rather than insisting we need someone else.
Turns out, we were right all along, and Biden doesn't understand the stakes, and is totally fine losing so long as he 'gives it his all'.
He won't pack the court. He won't do anything to forestall Project 2025. He'll just pat himself on the back behind his lifelong Secret Service protection and tell himself there was nothing he could do but hand the country over to a dictator.
Edit: Polling - released by Biden's campaign to try to prove his electability - shows other Democratic candidates right now performing just as well or slightly better than Biden with voters, and none of them have been running a campaign for the last year. In other words, without even trying, they are on par with Biden, and none of them have the baggage he does.
