Let's not start the unskewing crap, because we all know how that ended that time. This is not the first poll to show South Carolina in single digits, even the Republican firm Gravis shows it close. The fact that South Carolina is even this close goes to show that this election is practically over.
To be fair, a public poll commissioned by a party is basically one half step from a campaign internal poll. Lots of observers, including myself, exclude partisan polls. (You're right that nonpartisan polls are showing a close race too.)
