Addressing a crowd here for nearly half-an-hour, he thanked the people for turning out in massive numbers and said: "What voters here in New Hampshire confirmed tonight is nothing short of the beginning of a political revolution."
He said people would not accept a "rigged economy" and spoke of raising the minimum wage to $15 an hour if he was elected as the next president. The 74-year-old politician, who has put a serious emphasis on socialist ideology in his campaign, said the US belonged to all people and not just a few wealthy sponsors of the campaign.

Sanders, who finished very close to former secretary of state Hillary Clinton in Iowa caucus last week, ended up with 60 per cent votes in New Hampshire, defeating the latter (39%) by a wide margin.
