The candidates are criticizing the incumbents on domestic issues such as the sluggish economy, but they also say they have the moral authority to challenge their opponents for giving President Bush lockstep support on the five-year war in Iraq.
"When you add all of the guys up together, we've probably got close to 75 years of combined military service," said Bill Jones, a former Air Force officer from Marietta who is planning to launch a campaign this week against Rep. Tom Price of Roswell. "I'm excited about the idea of veterans stepping up and representing the Democratic Party."
Mr. Jones, 53, and the other challengers face long odds. They are political newcomers with little name recognition, running in conservative districts that routinely elect Republicans by wide margins.
In all but one case, they face established incumbents with well-stocked campaign treasuries.
But they say they sense that voters are looking for something different. Some believe Barack Obama, if he's the Democratic presidential nominee, could add to that dynamic.
Despite public dissatisfaction with the war, Democratic veterans have not fared well as congressional candidates. In 2006, only a handful won seats, including just one Iraq veteran, Patrick Murphy, of Pennsylvania -- despite the party's boasting that more than 50 veterans were running.
Among the Georgia Republicans being challenged, Jack Kingston of Savannah, John Linder of Duluth, Phil Gingrey of Marietta and Mr. Price each took roughly 70 percent of the vote in 2006. Paul Broun of Athens narrowly won his seat after the death of former Rep. Charlie Norwood, but his biggest challenge was from within the GOP.
Mr. Kingston said the challengers might get some initial attention as a result of their military service. But he said conservative voters will be turned off once they get to know the candidates' Democratic positions.
"If their views aren't consistent with the district, then they're not going to get very far," he said.
