Georgia Democratic Senate candidate Michelle Nunn raised more than $1.6 million in the last three months of 2013, bringing her total haul to $3.3 million since she jumped into the race in July.

More than 10,000 people have now donated to Nunn's campaign for the seat being vacated by the retiring Sen. Saxby Chambliss (R-Ga.), according to the her campaign. Seventy-eight percent of the donors who gave to Nunn in the fourth quarter donated less than $100.

Jim Galloway of the Atlanta Journal-Constitution called it "a big fundraising quarter" showing that Nunn hasn't "lost the momentum since entering the U.S. Senate race this summer."

"This campaign is about doing things differently and the broad and diverse group of Georgians joining our effort proves it," Nunn said in a statement. "Thousands of grassroots supporters, many Georgians who have never supported a candidate before, and a number of Republicans are joining our campaign to replace the political bickering and gridlock in Washington with pragmatism and problem-solving."
