Elections
Rather than run for a tenth term in the House of Delegates, Griffith opted to challenge Congressman Rick Boucher, a 13-term incumbent Democrat who had served since 1983. His home in Salem was just outside the 9th's borders at the time, but the district included almost all of his House of Delegates district.
Griffith chose to run for Congress after Boucher voted for the cap and trade bill. Boucher capitalized on the fact that Griffith did not live in the district, and in return Griffith branded Boucher as a rubber stamp for Barack Obama and Nancy Pelosi. Griffith won the election by less than 5% of the vote. Americans for Prosperity, an advocacy group funded by oil magnates Charles Koch and David Koch, spent heavily in advertising against Boucher, accusing him of betraying the district's coal industry.
Griffith defeated Democratic nominee Anthony Flaccavento, 61.3% to 38.6%.
Griffith defeated independent candidate William Carr, 72.1% to 24.2%.
Griffith defeated Democratic nominee Derek Kitts and Independent Janice Boyd with 68.59% of the vote.
Griffith defeated Democratic opponent Anthony Flaccavento 65.2% to 34.7%, with 223 write-ins among 246,989 votes cast. (A "Modern Whig Party" had endorsed a candidate whose name ultimately did not appear on the ballot and is listed at Ballotpedia as a "withdrawn or disqualified" independent.)
Griffith ran unopposed. He was reelected with 94.39% of the vote.
