No matter who is selected by the DNC, we can all rest easy knowing that it won't be anyone that the public had the opportunity to vote for, but that the public will still be at fault when that candidate isn't selected by the electoral college. This is Democracy™. We must all vote for the king's chosen successor, and pray that our votes please the council of elders.
The DNC is stuck between a rock and a hard place because they definitely have people available who have a better chance of winning (if only slightly), but it's going to look REALLY bad if they don't pick her.
