Dan Boren (D-Okla.), the four-term conservative representing Oklahoma's Second Congressional District, won't be seeking reelection in 2012, the Hill reports:
Boren, the only Democrat in Oklahoma's five-seat House delegation, will announce his decision at a press conference in Muskogee, his hometown, according to The Oklahoman.
"I never had any idea that he was not planning to run for reelection," said Wallace Collins, the state party chairman.
The 2nd district went for Sen. John McCain (R-Ariz.) in the 2008 presidential race by more than 30 points. Boren was one of the few Blue Dog Democrats to survive the GOP wave in the 2010 midterms.
Boren has only voted with his party 48 percent of the time this Congress, according to the Washington Post's data. He voted against the Democrats' health care legislation in 2009, as well as the Dodd-Frank financial reform legislation later that same year. Boren voted for the 2009 stimulus package.
Boren, a pro-life, lifetime NRA member, is perhaps the most conservative Democrat in the House. His father, David, is the current president of the University of Oklahoma and was once a U.S. senator and governor from that state. The younger Boren is only 37 years old and, despite his party affiliation, was still very popular in his district, where in 2010 he won by 13 percentage points over his challenger in a historic year for the GOP. Boren's retirement could mean a 2012 pickup of the seat for Republicans in deep-red Oklahoma.
