Rep. Patrick Murphy (D-Pa.), who led the push in the House to repeal the military's "Don't ask, don't tell" policy, lost his reelection bid Tuesday to former Rep. Mike Fitzpatrick (R-Pa.). 

Murphy, the first Iraq war veteran to serve in Congress, forcefully argued from his spot on the House Armed Services Committee to change the policy banning gay soldiers from serving openly in the military. 

Pennsylvania's 8th congressional district is one of the nation's consummate swing districts, taking in a good part of Philadelphia's suburbs. Murphy's loss not only tracks with what is shaping up to be a big Republican wave, it signals some potential trouble for Rep. Joe Sestak (D) in the Senate race.
