If the Potomac primaries go his way, and if they do by anything like the margins of last night, the dynamic of the race changes. It becomes a matter of whether a hard-won close victory by Obama can be derailed by the Clintons' super-delegates. It shouldn't and I'm pretty sure it won't. But you'll have to hold both Clintons down and pry the nomination from their vise-like grip before that happens:
The results in Washington and Nebraska vindicated Obama’s strategy of preparing expensive efforts to organize votes after the Feb. 5 contests that many expected wrongly effectively to decide the race. Clinton’s campaign, meanwhile, played down its own efforts in the states, though she did air television ads in both Washington and Nebraska.
Obama also won in Louisiana, buoyed by taking nearly 90 percent of the support of black voters, according to exit polls. And he won overwhelmingly in the U.S. Virgin Islands, winning all three of the territory’s pledged delegates.
In squeezing every delegate out of the small and mid-sized states between now and March 4, and every dollar out of his supporters, Obama is hoping to build a head of steam this month that will make him unstoppable and will lure free-floating superdelegates to his camp.
He hasn't just out-dreamed her. He has out-campaigned her.
