I understand that take but I see it differently. It’s not about whether he was/is/can be a good president. It’s about whether he can be an effective campaigner. Can he be a warrior against Trump, make the case, twist the knife, stop him? That to me is the only question. I think Biden has good days and bad, but on bad days the answer is clearly no. I don’t think a new candidate would necessarily be ‘chaos’, it could be energizing. Yes, even if it’s Harris. Just my take.
