When will South Carolina go Democratic in a presidential election?

[TDAS04]

Probably not for a long time, but before Alabama.  South Carolina was closer than people expected in 2008 and 2012, and a Democrat was almost elected Governor in 2010.  It has more people moving in from outside than the mid-south, so it's more likely to change than states such as Alabama or even Tennessee.  I would guess 2028, but that still might be generous.
