2010 Virginia's 11th congressional district election
The result was too close to call immediately following the election. At the end of the day on November 2, Connolly led Fimian by only 487 votes, with canvassing and certification still to be completed. After canvassing was completed and results from two outstanding precincts and provisional ballots were counted, Connolly increased his lead to 921 votes (0.41%). Although Virginia election law allows the losing candidate to request a recount on November 22 if the margin is less than 1%, the recount is at the government's expense if the margin is less than 0.5%, and the Fimian campaign had alluded to the possibility of a recount in a statement, Fimian eventually conceded the race to Connolly on November 9. Connolly won by 981 votes, or 0.43%.
The 2010 race was a rematch of the 2008 race, when Connolly defeated Fimian 55% to 43%. Connolly was unopposed for the Democratic nomination.
Fimian faced a primary challenge from moderate Fairfax County Board of Supervisors member Pat Herrity. A bruising primary fight ensued and The Washington Post described the race as "one of the nastiest contests in the commonwealth," with each campaign accusing the other of negative campaigning. Fimian emerged victorious, beating Herrity 56%-44%, with 35,890 votes cast.
The race was closely watched; it was considered a bellwether battleground district in the larger Republican mission to regain a majority in the House. The National Republican Congressional Committee picked Fimian for its Young Guns candidate training and support program.
