Here's today's key story out of the South Carolina local press: The Spartanburg Herald-Journal reports that Hillary Clinton will be visiting Spartanburg tomorrow, where she'll announce a big endorsement — but the Hillary campaign aren't saying just who the new endorser is.

Neither of South Carolina's two Democratic Congressmen represent Spartanburg, so it's probably not one of them. But the campaign must have viewed it as an important person if Hillary is showing up for the event, in light of how hard she and Barack Obama have been competing for votes in the first Southern primary.
