A survey of the Georgia Senate runoff by Public Policy Polling shows incumbent Saxby Chambliss (R) ahead of Democrat Jim Martin.

The PPP survey has Chambliss at 52 percent and Martin at 46 percent. The margin of error is 3.3 percentage points.

The Democratic Senatorial Campaign Committee had touted its own poll earlier on Monday that showed Chambliss barely leading, 48 percent to 46 percent.

The runoff will be held Dec. 2. Chambliss bested Martin during the general election, 49.8 percent to 46.8 percent. A candidate needed a majority of the votes to avoid a runoff.
