All of the networks instantly called the race for Hillary Clinton as polls closed at 7:30 p.m. The only question now is what her winning margin -- and pledged delegate haul -- will be.

Clinton's camp might be hurt tonight by overblown expectations. Bill Clinton suggested last week that the New York Senator might be able to pull 80% in West Virginia, and a top backer, the president of the State Senate, said the same. Barack Obama picked up on that in a press conference in Oregon over the weekend, suggesting that 80% is the bar for Clinton. Yet again, the margin matters, and the Clinton camp could find themselves on the losing end of the expectations game.
