That makes sense. OK-2 is the only House seat the Democrats have currently in the state, and barring a major Republican catastrophe, I don't see it changing anytime in the next 6-10 years, sadly.
They could probably turn Tom Cole(OK-04)'s seat Democratic(almost as much as OK-02) by lopping off Canadian and Commanche counties as well as the Oklahoma county portion and replace it the African American and blue collar neighborhoods in Oklahoma city as well as Seminole county.
Cole would have lost to Daryll Roberts in 2002 under this map.
