MANCHESTER, N.H.—Republican Donald Trump and Democrat Bernie Sanders rode a wave of voter frustration with American politics to commanding victories in Tuesday’s New Hampshire primaries, adding crucial credibility to their upstart candidacies.
Sanders swept majorities of men, women, independents and young people in his win over Hillary Clinton, but faces challenges in the more diverse states that come next on the primary calendar. Trump, appealing to voters seeking a political outsider, could benefit from the persistent lack of clarity among the more mainstream Republicans struggling to challenge him.
“We are going to do something so good and so fast and so strong and the world is going to respect us again, believe me,” Trump said at a victory rally.
