Oklahoma has five seats in the House, apportioned according to the 2000 United States Census. This election was the final one held in which Congressional districts apportioned according to the 2000 U.S. Census data. Representatives are elected for two-year terms; those elected serve in the 112th Congress from January 3, 2011 until January 3, 2013. As of 2016, this is the last time that a Democrat was elected to congress from Oklahoma.
This district is represented by Republican John Sullivan. Republican candidates, Craig Allen, Nathan Dahm, Fran Moghaddam, Kenneth Rice, Patrick K. Haworth and Independent Angelia O'Dell all have filed to run against Sullivan. Sullivan entered the Betty Ford Center in California to receive treatment for his addiction to alcohol on May 28, 2009.
This district is represented by Democrat Dan Boren. Democrat Jim Wilson and Republicans Daniel Edmonds, Charles Thompson, Chester Clem Falling, Daniel Arnett, Howard Houchen, and Raymond Wickson all filed to run against Boren.
Despite the poor approval ratings of Obama, of whom 27% in this district approve, and the high unpopularity of the Democratic healthcare bills, which were opposed by 17% of second district residents, conservative Democrat Boren remains popular.
This district was represented by Republican Mary Fallin, but the seat was opened as she has announced her candidacy for Governor of Oklahoma. The seat attracted the attention of several Republican candidates, including State Representative Mike Thompson, former State Representative Kevin Calvey, whom Fallin defeated in the 2006 Republican primary for this seat, physician Johnny Roy, who also ran in 2006, Harry Johnson, Rick Flanigan, Shane Jett and Baptist General Convention of Oklahoma  employee James Lankford, as well as Democrats Tom Guild and Billy Coyle. Ultimately Republican James Lankford and Democrat Billy Coyle won their respective parties' nominations and will face off in the general election in November.
