Sanders has a lock on old commies and young empty-heads.
Butt-Geiged appeals to Dem women voters. He’s young/energetic and openly gay, seems to be just so-edgy. Women see Butt-Geiged as another JFK or Obama(!?) and showcase their own tolerance and open-mindedness to their peer. (Don’t understand the appeal personally, but whatev!)
If Bloomberg managed to buy his way into Dem nomination, where is he going to peel voters from, to overcome Trump?
As for other Black Horse/Uniter, there’s always a chance, but I don’t see it in the near horizon.
And in this corner, introducing the unspoken by everybody, the Black Uniter Woman Billionaire OOOOOOOOOPHRAH!
