Jim Martin (D): 46
Saxby Chambliss (R-inc): 50
(MoE: ±4%)
So far, both publicly-released runoff period polls (R2K being the other) have showed little movement since November 4th. Chambliss still retains a slight lead, but as Nate Silver says, likely voter models are tough to set for special-type elections, and it's difficult to make assumptions about turnout. Incredibly, 88% of Georgian voters say they are "certain" to vote in this runoff, which is a bit hard to believe considering that voter turnout was over 20 points lower on November 4th. In this race, so much will come down to getting out the vote, making the outcome difficult to predict.
I'm told that another pollster is about to go into the field here tomorrow, so we should have some more poll results to pick apart in a few days.
