Chris Murphy Beats Wrestling Exec. Linda McMahon in Costly Conn. Race

Nov. 6, 2012— -- Democratic Rep. Chris Murphy beat out former wrestling executive Linda McMahon for a U.S. Senate seat from Connecticut in the costliest race in the state's history.

ABC News is projecting Murphy as the winner of the Senate race against McMahon, who outspent the congressman by more than $20 million, sinking some of her own fortune into her $42 million bid.

McMahon, who ran World Wrestling Entertainment before throwing her hat into the political ring, previously spent $50 million running for Senate in 2010.

Murphy spent about $20 million on the race. He has served as a Congressman for Connecticut since 2006, and was tapped to run for Sen. Joe Lieberman's seat, who announced in 2011 that he would not run for reelection. Lieberman ran as an independent and caucused with Democrats.

The costly race turned bitter on both sides throughout the campaign, as McMahon shed light on a property owned by Murphy which faced foreclosure and Murphy showed that McMahon was late paying property taxes multiple times.
