Scott Brown (R), a Republican candidate for the U.S. Senate, listens to a question from the audience during a town hall campaign stop at a VFW post in Hudson, New Hampshire September 3, 2014. Until five years ago, Brown was a little-known Massachusetts state representative who trained for triathlons in his spare time. But in early 2010 he stunned Massachusetts liberals by beating the state's attorney general, Martha Coakley, to claim the U.S. Senate seat held for half a century by Edward M. Kennedy.After losing his 2012 re-election bid to Elizabeth Warren, Brown late last year moved north to the state where he grew up, with an eye on running again. Picture taken September 3, 2014.
