Beshear in KY, Steve Cohen and Jim Cooper in TN are still around and will be for a long time.
Well Beshear is a governor. There are no guarantees he would win if he ran for a Senate seat. Same with Mike Beebe in Arkansas (who is beating Boozman in polls in a 2016 hypothetical match-up).
Cohen and Cooper are from Memphis and Nashville respectively. Louisville also has a Democrat in the House. Most large Texas cities also have Democratic representatives. Southern cities are still Democratic, there just aren't as many cities down there I guess.
