It doesn't matter which candidate can claim most states won, pledged delegates or popular vote. As we've heard time and again, it's like suggesting it matters in an NFL game who will wind up ahead on total yardage, red-zone scoring, and turnover differential -- excellent outcome predictors usually -- when one team will clearly end up with more points.
The winner of the Democratic primary will be the one with the most delegates. Period. There is no rule saying how the superdelegates have to vote. That was the whole point in creating the rules we're now operating under. Obama will win because he will have won the most delegates -- not because he will have won the most pledged delegates or the most states.
The reason he will win is because he worked hard to persuade committed activists in caucus states; he worked hard to raise enough money from committed activists to be competitive in the primary states with a less-tuned in audience who needed his message to be spoon-fed to them through endless tv ads. He's working hard behind the scenes to persuade superdelegates that, not only does he have a better chance to beat McCain, but he also will help enormously with down-ticket races.
Clinton is doing a pretty darn good job of sewing confusion about metrics as a means to persuade superdelegates, because she knows it doesn't matter what type of delegates you get, it's how many. She could win that way -- by getting lots of supers, and if she does, great. She's not overturning the "will of the party." She's winning any way she can within the rules. But she won't. Obama just out-worked her.
