Show me where there is anything even close to an admission of being wrong? Where is he saying that running again was a mistake and that the party needs to be looking to younger members to take them into the future?

Biden isn’t apologizing for the waste of campaigning up to this point. He got COVID again and combined with the massive push due to the clearly pertinent age-related health questions, there’s just no option to keep going. He’s only dropping his bid because it’s being forced.

He’s not leaving because he wants to, or because he’s had any sort of realization.
