Joe is old and not really “all there”...why doesn’t he just drop out of the race? This really can’t be worth it. I have a feeling he didn’t even want to run by the DNC begged him because they don’t want Sanders/Warren as head of the party.
IMHO, I think the old-time democrats (well, the ones who haven’t decided to vote for Trump) want Biden to get the nomination, but the progressive radicals want a progressive radical, and they don’t care which one, as long as they think she can be elected. The democrat party has a philosophical split, but many will vote for anyone with a D behind their name; the dilemma is, just how many of those are there?
