Despite some noise during Georgia’s primary season, Peach State incumbents appeared to have little trouble wrapping up their party nominations Tuesday night.

In the central Georgia 12th district, Rep. John Barrow (D) was being challenged by a well-known black state legislator in a district that is 45 percent black. But the white two-term Congressman trounced state Sen. Regina Thomas in his closely watched primary battle. Barrow, who was buoyed by the endorsement of Democratic presidential nominee Barack Obama last month, led 77 percent to 23 percent with 74 percent of precincts reporting.

Barrow will likely face John Stone, a radio personality and former Congressional aide, who was leading a three-way race for the GOP primary with 59 percent of the vote with 74 percent of precincts reporting.

Farther north in the Augusta- and Athens-based 10th district, Rep. Paul Broun (R) had little trouble dispatching state Rep. Barry Fleming (R), despite Fleming earning the backing of large numbers of state legislators. With 91 percent of precincts reporting, Broun led 72 percent to 28 percent.

And in the Atlanta-based 5th district, Rep. John Lewis (D) had no problems earning a nomination to a 12th term in Congress over two younger challengers who attacked him for backing Sen. Hillary Rodham Clinton (N.Y.) in the Democratic primary before he switched his endorsement to Obama. With just 41 percent of precincts reporting, the Atlanta Journal Constitution has already called the race for Lewis.

Rep. Jim Marshall (D-Ga.), who faces a competitive general election battle, easily won his primary Tuesday, and Rep. David Scott (D-Ga.) is on course for a primary win.
