According to various media sources, Oklahoma's Second District Congressman Dan Boren is not going to run for re-election. He is expected to announce his "retirement" at 2 PM in Muskogee.
Just hours after the story was published, former Representative Brad Carson announced that he would run for his old seat. Other names being thrown around on state blogs are former state senator Kenneth Corn and current state senator Jim Wilson, who ran against Dan Boren in the 2010 primaries.
Personally, I think it's going to be very hard for the Democrats to keep this seat, especially if the Republicans can recruit a decent candidate.
