Former Speaker of the House Newt Gingrich speaks during the National Rifle Association's 139th annual meeting in Charlotte, North Carolina in this May 15, 2010 file photo. Minnesota Governor Tim Pawlenty, former Massachusetts Governor Mitt Romney Gingrich are among the high-profile figures to visit New Hampshire recently, which wields out-sized political sway by holding the first U.S. presidential primary. This season nearly a dozen top Republicans have visited the state, not for the colorful leaves but to gauge support for possible 2012 presidential bids.
