I may well be wrong in assuming Biden will last until the convention.
There is no way the dems are going to try HRC again - the Bernie Bros would vote en masse for Trump or stay home. Michelle is not giving up easy street for the most stressful job on planet Earth. I have never believed Biden would emerge from the convention as the winner unless they are totally conceding the race which doesn’t add up either because Biden at the top of the ticket really could cost them the House. So who’s left? I give up. Oprah? They have no good options. Couldn’t happen to a nicer bunch...
