I hope you’re right. If I were a betting man, I’d say
Trump 57/43 Clinton (if Sanders isn’t VP)
Trump 52/48 Clinton (if Sanders is VP)
Trump 51/49 Sanders
Biden 53/47 Trump
Though The Biden Solution for Dems is probably their best political "compromise," the DNC's problem was in waiting too long to implement Uncle Joe. I still believe he'd be even more defenseless and look just as stupid going up against the salvos of Trump.
Since both The Hag Camp and Commie Camp are spiteful, petty, and maniacal, I don't see their respective machines all that much helpful to Biden. Ironically, BOTH will feel he stole the nomination from Hillary AND Bernie.
