The Clinton camp is well apprised of the situation. You don't bow out in the immediate aftermath of a landslide victory over your opponent.

Also, the math that matters most to them now--the financial side--she benefits most by staying in until the convention, so she can work over summer to retire some of her debt.

So I'd say they are still running a very good campaign, actually. It is nothing to sneeze at, what she accomplished in West Virginia, and the Democrats ignore that to their own peril.

Which is what they usually do anyway, so it all looks pretty much the same as it did last week to me, despite the Edwards endorsement.

Edwards was waiting to see who won North Carolina before he declared. Once it was clear Obama could still win a big victory, it was safe for him (Edwards) to endorse. He wasn't about to back the loser, that's for sure. Not if he intends another run for the White House.
