Difference of white vote and actual vote

[TDAS04]

Why are SC whites the most democratic in the deep south? I thought SC was the most hardline pro-slavery/pro-confederate state, the solidest of the solid south, and turned Republican comparatively quickly in the modern era.

More northern transplants than AL, MS, & LA.

West Virginia whites are more Democratic than North Carolina whites.  Kind of interesting when you think about it, considering that Obama almost carried the latter state in 2012 (and actually carried it in 2008).
