Hillary Clinton, who lost her front-runner status when Barack Obama won the first Democratic nominating contest in Iowa, teared up briefly during a campaign stop in New Hampshire, the next state to hold a nominating contest.The rare show of emotion came when a supporter asked how she handled the pressure of running a national campaign. The moment helped to humanize her for voters, especially women. She ended up winning the state's primary election, briefly stopping Obama's momentum and setting up a months-long battle for the Democratic nomination.
