Even though Sanders is now poised to win, I think we have to turn our attention to the possibility of an open Democratic Convention. In the event that two current candidates are too close to call in pledged delegates, and the super delegates exercise their prerogative to keep their powder dry, I can easily envision a situation in which Biden emerges as the unity candidate.
Joe Biden has the charisma and horse trading skills to pull it off. Clinton people would get something (VP Spot?), the Sanders people would get something (cabinet spots), and best of all the American people would get a Democratic Party ready to lay waste to whichever douchebag piece of shit the GOP decides to go with.
