Obama has won: Deleware, Georgia, Illinois, Kansas, and Alabama
Clinton: New York, New Jersey, Oklahoma, Tennessee, Massachusetts, and Arkansas
Romney: Massachusetts
McCain: New York, New Jersey, Deleware, Illinois, Connecticut
Huckabee: Arkansas, Alabama, West Virginia
Keep in mind that, on the Democratic side, the delegate count is extremely important and still extremely unknown. As Jon Cohn noted:
keep in mind what this is really all about: delegates. And in close states like Massachusetts and New Jersey, it's entirely possible that Obama will get plenty of delegates -- nearly as many, in fact, as if he had won it. (In fact, I suppose it's possible he'll win more delegates.)
That said, I'm impressed Clinton seems to have held on in both states. Of course, I'm also impressed that Obama closed the gap as much as he did.
Am I being completely wishy-washy about this? Why, yes I am.
And he's a fair-minded observer if ever there was one.
