OKLAHOMA CITY - Oklahoma Democratic Party chairman Wallace Collins says former U.S. Rep. Dan Boren is considering running for Tom Coburn's U.S. Senate seat. But according to the Associated Press, Boren will not run for the seat.

Boren served four terms as a U.S. Congressman and was the last Democrat to serve in Oklahoma's congressional delegation. He decided not to seek re-election to his U.S. House in 2012 and currently works for the Chickasaw Nation as president of its corporate development department.

Boren isn't the only prominent Oklahoma Democrat to take his name out of the running for the U.S. Senate seat. Former Lt. Gov. Jari Askins and longtime Chickasaw Nation Gov. Bill Anoatubby each told The Associated Press they have no plans to run for the seat.

Former Gov. Brad Henry and former Attorney General Drew Edmondson -- both Democrats -- did not immediately return telephone messages from the AP.

Former Democratic state Sen. Kenneth Corn of Poteau said he is considering entering the race.
