Voting is underway in Georgia, where there are 14 candidates — seven Democrats and seven Republicans — vying to win their party’s nomination for governor. 

On the GOP side, a new poll shows state Insurance Commissioner John Oxendine slipping to fourth place after leading the pack for much of the race. The Sarah Palin-backed Karen Handel, meanwhile, leads in a InsiderAdvantage/WSB poll with 28 percent.

She’s had the lead in some other surveys completed since Palin made her endorsement on Facebook July 12.

Former Rep. Nathan Deal (R-Ga.) and former state Sen. Eric Johnson get 17 and 14 percent respectively in the latest poll. 

If none of the candidates break 50 percent, the top two will be forced into an August runoff.

Former Gov. Roy Barnes (D) is widely expected to win the Democratic nomination without having to go through a runoff. 

Polls close today at 7 p.m.
