From Chris Cilllizza at the Washington Post:
With Edwards out of the race, the Democratic fight becomes a true two-person affair with Obama and Clinton battling one another for delegates on Super Tuesday and, in all likelihood, beyond. As we wrote earlier this week, Edwards' Super Tuesday strategy of focusing on states in the South and with significant rural populations seemed to make Obama's path rather than Clinton's more difficult over the coming weeks.
Edwards' departure also likely means a further coalescing of the anti-Clinton vote behind Obama -- recent votes seemed to show that process was already well under way. But race could also shape this unsettled contest, and potentially complicate the formation of an anti-Clinton coalition.
"While one can plausibly argue that Edwards withdrawal may unite the anti-Clinton vote, one can also argue that Edwards overwhelmingly white block of supporters come loose and might behave much as other white Democrats have done in the contests after Iowa, not vote for Obama," said Charlie Cook, a political analyst and publisher of the Cook Political Report. "I don't know which of those arguments will prevail."
