U.S. Rep. Phil Gingrey has won a crowded GOP primary in Georgia's 11th Congressional District and will be a favorite to win a sixth term when he meets Democrat Patrick Thompson in the Nov. 6 general election.

Unofficial returns on Tuesday showed the Marietta congressman with 80 percent of the vote with 37 percent of precincts reporting. Marietta arbitration and mediation specialist Michael Opitz and Sandy Springs accountant William Llop each had 10 percent.

Thompson, a 55-year-old sales manager from Roswell, had no opposition in the Democratic primary.

Gingrey's district was redrawn last year to become more compact in the metro Atlanta area. The boundaries include several suburban counties northwest of the city.
