After tonight, Hillary Clinton will be leaving South Carolina, not to return until Friday. In her place, Bill and Chelsea will be campaigning through the state (but I’d be surprised if either one stick it out the whole week, either). I think it’s a recognition of the realities on the ground here. Obama has got a healthy lead that’ll be hard to narrow, much less overcome.

At the same time, Obama’s folks know what happens when the expectations game favors their guy.
