Knowing how stupid and petty Georgia Republicans are, I wouldn't be surprised if Democrats gained seats. Currently, two of the three closest split districts have Republican majorities, but have Democrat Reps. Instead of working to win both of those districts, the State House Speaker ceded one to the Democrats to make the other even more Republican.
If the Republicans quit their petty BS and instead decided they wanted to win elections, they could pick up all three and get rid of Sanford Bishop. That would switch from an 8-6 split to an 11-3 split, a 6-seat gain. So that and North Carolina alone would win back the House. Unfortunately, the Georgia GOP doesn't give a damn about any of that.
