Well, it looks like Jim Whitehead might be the next Congressman. There are 1700 votes still to be counted in Columbia and, in my experience, the runoff absentee votes generally favor the primary winner by a significant margin. There are also a few votes uncounted in smaller counties.
[UPDATE by Erick:] There appears to be only one outstanding precinct left, contrary to the AJC report. That would be provisional ballots and those aren’t going to help Whitehead.
