Donald Trump won the key New Hampshire primary Tuesday, moving him ever closer to locking in the Republican presidential nomination and securing an extraordinary White House rematch with Joe Biden. With vote counting ongoing, it was unclear if Trump had secured the knockout victory to put his sole remaining challenger Nikki Haley out of the contest.In a speech following the vote, the former UN ambassador during Trump's frequently chaotic presidency said the race was "far from over" and told supporters that Democrats "want" to run against her former boss.
