The Republican nominating contest to succeed Sen. Saxby Chambliss has narrowed into a virtual three-way tie, according to a new InsiderAdvantage survey.

The poll, released Thursday, found Reps. Jack Kingston, Phil Gingrey and former Secretary of State Karen Handel bottlenecked in the mid-teens, the three registering within the margin of error.

Kingston maintained a slight edge, pulling the support of 17 percent, while Gingrey and Handel followed closely behind at 15 and 13 points respectively.

Outspoken conservative Rep. Paul Broun narrowly crested double digits, at 11 percent, and businessman David Perdue, who is not yet an official candidate, pulled only single-digit support.

The poll additionally measured partisan sentiment toward Gov. Nathan Deal, who netted a primary challenge earlier this week from Dalton Mayor David Pennington. Only 8 percent said they would vote for Pennington over Deal in a primary bout for the governor’s mansion.

The survey was conducted July 10 and included a sample of 338 registered voters. The margin of error is 5.3 percent.
