Rep. Phil Gingrey and former Dollar General CEO David Perdue are also running in the primary for Sen. Saxby Chambliss (R)'s seat, who is retiring.

Recent polling has shown Perdue, Handel and Kingston as the likely leaders in the crowded primary. If no one attains 50 percent of the vote, the top two performers would have to go to a run-off election.

Michelle Nunn is the frontrunner for the Democratic primary.
