Oklahoma Democratic Rep. Dan Boren will not run for re-election in 2012, The Oklahoman reported Tuesday.
Boren, a Blue Dog first elected to represent the state’s 2nd Congressional District in 2004, succeeded former Democratic Rep. Brad Carson.
Carson announced Tuesday that he will run again to represent the district, which is located in the eastern part of the state. Carson did not seek re-election to the House in 2004 to instead challenge Republican Senator Tom Coburn.
Boren is the son of former Sen. David Boren, who also served as Oklahoma’s governor.
Boren has been among the most conservative Democrats in the House. He voted against the 2009 health care reform act and serves on the board of the National Rifle Association.
John McCain carried the district with 66 percent of the vote in 2008, suggesting that Republicans could pick up the seat. However, Boren also won handily in 2008, with over 70 percent of the vote.
