There is no way to predict this state because of it's legendary vote fraud system. Voting is totally electronic, which then gets transmitted to a secret location, no receipts, paper trail, or verification system of any kind. At least in Iowa and NH through the tireless efforts of Watch The Vote 2012, the fraud is being exposed and is now beginning to be reported. Don't know if Watch the Vote or Black Box Voting have any plans for SC, but I hope there is something they can do. Otherwise the vote totals are going to be what the computer programmer and the SC GOP set it up to be.
