Former Massachusetts Gov. Mitt Romney gives the keynote address at the New Hampshire Republican Party State Convention in Concord, New Hampshire in this September 25, 2010 file photo. Romney, Minnesota Governor Tim Pawlenty and former U.S. House of Representatives Speaker Newt 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.
