Race in the South

The Democratic Strategist:

...I think Nate's on to something, based on some very specific numbers. In 2004, Kerry's share of the white vote in Mississippi and Alabama was 18%, and was 22% in South Carolina. This year Obama's share of that vote sank to 11% in Alabama, and 10% in Mississippi, yet rose to 26% in South Carolina.

...Perhaps SC's recent economic growth, accompanied by a significant if not overwhelming number of transplants, has separated it a bit from the rest of the "super-south." But if so, not by much, and there's nothing there like NoVa's large and essentially non-southern voting base, or NC's Research Triangle concentration of "latte class" professionals and students.

So why did the white vote in SC go in exactly the opposite direction in 2008 as MS's and AL's? Nate thinks it may be because South Carolinians had a heavy personal exposure to Obama (and his family; his wife's roots are in the state) during the primary campaign, and thus saw him as less alien than did southern white voters elsewhere in the Deep South.
