MANCHESTER, N.H. (AP) - Republican Donald Trump and Democrat Bernie Sanders swept to victory in Tuesday's New Hampshire primaries, adding crucial credibility to their upstart candidacies and underscoring voters' insistence on shaking up American politics. Trump and Sanders entered Tuesday's contest as favorites in New Hampshire, but needed to deliver on expectations after second-place finishes in Iowa's leadoff caucuses. Trump appealed to voters seeking a political outsider, while Sanders was buoyed by those seeking a candidate who they felt cared about people like them.
