Gardner. He shouldn't even be going to the upper chamber, but he is on account of his fake views and soon-to-be broken promises.
Tillis and Lankford are also among my least new favorites for obvious reasons.
Gardner is going to be fairly moderate once he gets to the senate. Just watch. In the 4th district, he could afford to be more or less aligned with the Tea Party, but now that he holds a statewide office in which reelection isn't automatic, as a result of campaigning as a moderate, I expect him to move substantially to the left of where he was in the house, unless he actually WANTS to lose in six years, which I doubt.
