FINAL TOTAL 54% TO 45.5%
From Eric Dondero:
It appears Ms. Colbert Busch did not get the necessary bounce she needed out of Charleston to take the whole district. Sanford held her to just about even there, and won big in outlying counties like Beaufort and Berkeley. This is a big win for the Republican Party.
Late breaking results suggest Sanford may even pull it out in Charleston County, which would be a stunning defeat for the SC Democrat Party.
If the GOP can win with a flawed candidate like Sanford, it bodes very well for other elections later this year (NJ & VA), and races going into 2014.
Note - libertarian Republican US Senator Rand Paul made a last minute endorsement of Sanford.
CNN's Elections Desk just called it for Sanford.
