In this photo taken Jan. 19, 2010, former Massachusetts Gov. and presidential hopeful, Mitt Romney, right, introduces and congratulates U.S. Senator-elect Scott Brown, R-Mass. at his Boston victory party after he won the seat vacated by the late Sen. Edward Kennedy. The two Massachusetts Republicans have a history of supporting each other throughout their political careers, but facing tough elections neither is playing up that history now, perhaps with good reason.
