Live coverage: Democrats vote in the New Hampshire primary
Barack Obama's vice president was meant to be the favourite for the Democratic nomination. Now, Joe Biden is suddenly in massive trouble.
Bernie Sanders has won the New Hampshire primary, solidifying his status as the new frontrunner for the Democratic presidential nomination.
It was Mr Sanders' second consecutive victory in the state, having racked up a whopping 60 per cent of the vote against Hillary Clinton four years ago.
This time, with far more candidates in the race, the result was much closer. Mr Sanders claimed 26 per cent of the vote, narrowly beating former South Bend mayor Pete Buttigieg, who finished with 24 per cent.
Minnesota Senator Amy Klobuchar, who was previously considered only an outside chance to win the nomination, reinvigorated her campaign by surging into third place with 20 per cent.
Massachusetts Senator Elizabeth Warren found herself a distant fourth, stuck in single digits with 9 per cent.
And shockingly, former vice president Joe Biden - supposedly the favourite for the nomination - finished even further behind in fifth, with just 8 per cent.
After Mr Biden's equally tepid performance in Iowa a week ago, and with the news that Mr Sanders has passed him in national polls, it's fair to say Mr Biden has now relinquished that frontrunner status.
Read on for all the news from a dramatic election night in the United States.
