Bernie Sanders has won the New Hampshire primary, the second stage in the Democratic race to find a challenger to President Trump in November's presidential election.
Sanders declared the night "the beginning of the end" of Trump.
But close behind Sanders was the former mayor Pete Buttegieg and also Minnesota senator Amy Klobuchar.
It was a disappointing night for Joe Biden, who came in 5th place. Brent Budowsky is a political columnist for The Hill.
