Vermont Senator Bernie Sanders won the New Hampshire primary on Tuesday, defeating former secretary of state Hillary Rodham Clinton to become the first Jewish candidate ever to win a presidential nominating contest. His victory is a political setback for Clinton, who won in Iowa on February 1 by less than half a percentage point. She nevertheless maintains strong leads in the states to come– including in South Carolina and Nevada, the next two immediate contests. Sanders and Clinton are in a head-to-head race after former Maryland Governor Martin O'Malley dropped out of the race last week. Eight candidates remain in the Republican contest.
