I was perusing the polls for various states and I happened to look at South carolina.

One thing I noticed is that only one poll had a registered voter model and that poll suggested that SC could be won by Obama (it was 4 months ago, which would normally bother me but the apparent decline in polling is a result of different polling outfits)
So as to the question of whether or not SC is in play I don't know. But such numbers should encourage people even in red states.
