From KMRG in Tulsa, Oklahoma: “Brad Carson posts on Facebook he will NOT run for Congress.”

This is the district where conservative Democrat Dan Boren is retiring. Carson represented the seat until he ran for Senate in 2004; he was seen as the Democrats’ best, and perhaps only, chance to keep the seat in a heavily Republican district in a presidential year. Under current lines, the district scores R+14 in the Cook Partisan Voting Index and it is Tom Coburn’s old district.

While nothing is 100 percent certain until the votes are cast and counted and the results are certified, this looks like a Republican House seat pickup in 2012.
