Sanford's numbers rebound

That new Rasmussen poll, showing Jim DeMint beating up on Alvin Greene, 64%/21%, also shows South Carolinians approving of the job Mark Sanford is doing by a substantial margin, 55%/43%.

In an interview with the WSJ last week, Sanford refused to rule out a return to elective politics. It's hard to imagine him having any shot at a '12 nomination now, but here's a thought: a run against Lindsey Graham in the 2014 GOP primary.

After all, a July poll showed only 32% of Republicans in SC would support Graham in a 2014 primary, while 57% would support a more conservative, unnamed candidate.

Might Sanford start thinking about himself as the unnamed, more conservative candidate?
