Vermont senator Bernie Sanders has won the New Hampshire Democratic primary contest, seemingly making him the forerunner for the 2020 presidential election.

Sanders, who ran unsuccessfully for president in the 2016 election which eventually led to Republican candidate Donald Trump assuming office, managed to attain a slim margin of victory over Pete Buttigieg.

According to a report by BBC News, more than 280,000 voters cast ballots in the Granite State on Tuesday night, delivering Sanders 26 per cent of the vote, while Buttigieg only attained 24.5 per cent.

In a passionate speech, the politician stated: "The reason I believe we are going to win, is that we have an unprecedented grassroots movement, from coast to coast, of millions of people."

Per CNN, he told the crowds: "The reason that we are going to win is that we are putting together an unprecedented, multi-generational, multiracial political movement. This is a movement from coast to coast, which is demanding that we finally have an economy and a government that works for all of us - not wealthy campaign contributors."

Meanwhile, the defeated Buttigieg stated: "In this election season we have been told by some that you must either be for revolution, or you are for the status quo. But where does that leave the rest of us? Most Americans don't see where they fit in that polarized vision, and we can't defeat the most divisive President in modern American history by tearing down anybody who doesn't agree with us 100 per cent of the time."

This news has come just a week after a video went viral on social media, which showed a voter deciding to turn against Buttigieg at a polling station after learning that the former mayor of Bend was gay.
