According to Marc Ambinder, "Hillary Clinton probably won the "popular vote" by a larger margin than six percentage points ... because Obama probably received the lion's share of re-allocated votes from Edwards supporters in non-viable precincts." That seems meaningful, though I'd like to know the demographics of the non-viable supporters (are they rural? And why, for that matter, did Obama do so well among rural Nevada caucuses? That wasn't his pattern till now.). Ambinder also writes, quite wisely, " is the Democratic primary a fight over delegates? At the lowest level of abstraction, yes. But at a higher level of abstraction, it's about expectations; it's about the marriage of popular vote performances by the winner and the will of the candidate who does not receive the support of a majority." Delegate counts will come into play if there's not a clear winner on Super Tuesday and we move towards a brokered convention.
