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, Trump’s margin of victory was unclear and his sole remaining challenger Nikki Haley was quick to insist she would fight on.

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.
