AMHERST, NH - JANUARY 07: Republican presidential candidate, former U.S. Sen. Rick Santorum gives a thumb up as he waits for the beginning of a TV interview after he spoke to voters outside Homestead Grocery & Deli January 7, 2012 in Amherst, New Hampshire. The meet-and-greet event was moved outside after too many people had showed up and exceeded the limit of the fire regulations. Santorum continued to campaign in New Hampshire for the upcoming primary election. (Photo by Alex Wong/Getty Images) less
