District 5

Incumbent Republican Congressman Ernest Istook declined to seek an eighth term in Congress, instead opting to run for Governor, creating an open seat. Mary Fallin, the Lieutenant Governor of Oklahoma, won the Republican primary and was favored to win the general election in this largely conservative district based in the Oklahoma City metropolitan area. Though Fallin was victorious on election day, her margin of victory over Democratic opponent David Hunter was the thinnest margin of any member of the Oklahoma congressional delegation.
