Here is some good commentary on SC win and how there may be a backlash to scorched earth politics of Clintons.

If I'm right, those voters were pretty clearly saying that they didn't like the kind of campaign the Clintons were running against a fellow Democrat. It's a rebuke for both Clintons that will force them to rethink their scorched-earth strategy toward Obama and that presents them with a conundrum.

I remember Tomasky, the author from some US blog. Which was it? Rght, he was editor of American Prospect. Thanks wikipedia.
