Rep. McNerney challenger concedes defeat

California Republican David Harmer has officially conceded defeat to Rep. Jerry McNerney (D-Calif.) more than a month after Election Day. 

McNerney was declared winner of the race by the AP more than a week ago and had already pronounced himself the victor, but it wasn't until late Friday that Harmer actually phoned the Democrat to concede. 

The final margin of victory for the incumbent was more than 2,500 votes.  

Harmer, who has run for Congress three times, told a local reporter that he has no plans to run again in the future.
