It wasn’t even that bad. He felt old, yes, but his responses were fine. They weren’t all great, but it was better than Trump spouting outright lies left and right that fed a dangerous narrative. I wouldn’t vote for Biden in a primary, but it seems too late to replace him now. There are legal entanglements and monies that can’t be transferred. Kamala is just not that strong a candidate for beating Trump. I don’t know who is at this point. It’s a terrible position to be in, but it seems like a Biden vs Trump race or a surefire loss to Trump.
