Former congressman Bob Barr won't be making a congressional comeback this year. He lost by a wide margin Tuesday in the Republican runoff for the U.S. House in Georgia's 11th district.

The Associated Press has called the race for tea party-backed state Sen. Barry Loudermilk (R), who led Barr 70 percent to 30 percent, with 41 percent of precincts reporting. Loudermilk was backed by the anti-tax Club for Growth.

Barr, who represented Georgia's 7th district in Congress for eight years, was at the forefront of the impeachment of Bill Clinton. He was also the Libertarian nominee for president in 2008.

Loudermilk is expected to coast in November -- no Democrat even entered the race in the conservative-leaning district.

The seat is being vacated by Rep. Phil Gingrey (R), who unsuccessfully ran for the U.S. Senate.

In the conservative 10th district, Baptist minister Jody Hice defeated businessman Mike Collins. Rep. Paul Broun (R), who also ran for Senate, is vacating the seat.

Broun backed Hice. Like the congressman, Hice is no stranger controversy. He's suggested that Islam "does not deserve" First Amendment protection.

In the 1st district, which Rep. Jack Kingston, a Senate candidate, is vacating, state Rep. Buddy Carter defeated tea-party backed retired Army Ranger and surgeon Bob Johnson. The Club for Growth backed Johnson.

Carter will face Democrat Brian Reese in November. The 1st district leans Republican.
