[ Clinton by 10 Pts. ]

There are going to be an infinite number of ways to spin Obama's 10-point loss to Clinton, but I do think it's relevant that three weeks ago, Obama was supposed to lose Pennsylvania by 20 points.

Scandal-laden April has been his toughest month yet. Still, he was still able to slice Clinton's lead in half. Obviously I'm biased, but I can't help but think that makes him one hell of a politician, a worthy adversary to McCain in the fall.

Obama's bigger problem, however, is that many Clinton voters will vote McCain when Obama gets the nomination.
