Do you honestly think he's going to be re-elected in 2016? He's had health issues and you know the Dems will do a full court press to get the seat back. He only one by a point or two to begin with.
I would guess he’ll retire, but his razor thin win in the blue state was similar to other victories in blue states. Toomey in PA, Brown in Mass.
I’m not saying the race is Iowa competitive, but if the candidate is good, I’m willing to give it a shot.
