Obama Takes Virginia

NBC just called it moments after the polls closed, as a "substantial" victory. This was Hillary's best chance at a good showing, so it's likely to be a bad night for him.

Also, McCain-Huckabee is too close to call in Virginia, and the exit polls intimate that Obama got a huge amount of independents, draining them from McCain in this open primary, raising Huckabee's number as that race becomes more conservative.

This could be 8 straight losses for Clinton since Super Tuesday, with Wisconsin and Hawaii looming next week. Ohio and Texas loom even larger now. Obama should be ahead in delegates, even with superdelegates, by the end of the night.
