Georgia voters are heading back to the polls for high-stakes primary runoffs as early voting approaches, with Republicans still unsettled in the marquee races for governor and U.S. Senate while Democrats rally around former Atlanta mayor Keisha Lance Bottoms, who plans a joint appearance with Sen. Jon Ossoff.

The GOP governor runoff between Lt. Gov. Bert Jones and businessman Rick Jackson has become one of the state’s most expensive and contentious contests, with Jackson skipping an Atlanta Press Club debate, while the GOP Senate runoff between Rep. Mike Collins and former coach Derek Dooley features late momentum, Gov. Brian Kemp’s support for Dooley, and renewed scrutiny after Collins’ campaign fired a staffer over an offensive social media post.
