Manchester, New Hampshire: Senator Bernie Sanders and Republican Donald Trump have won emphatic victories in the New Hampshire primary, with voters turning savagely on insider political figures in both parties.

Such was the size of their respective victories that US media outlets were able to confidently project their victories once the second polls closed at 8pm.

Sanders supporters at a campaign watch party in New Hampshire exploded with joy at the news, and cheered again minutes later when it was reported that Hillary Clinton, the Democratic front runner, was soon expected to call the democratic socialist senator from Vermont to concede to him.
