Mitt Romney changes his Twitter location from Massachusetts to Utah amidst Senate run speculation

The former Republican 2012 presidential nominee, 70, changed his location from Massachusetts - where he served as governor from 2003 to 2007 - to Holladay, Utah, where he owns a home. The change in location, which may appear seemingly benign, comes as speculation swirls that Romney may be interested in filling Republican Utah Sen. Orrin Hatch's Senate seat.
