It was an early start for presidential candidates in New Hampshire as voting began in the nation's first primary.

Hillary Clinton was greeted by an enthusiastic crowd outside a polling station in Manchester as she came to thank her supporters.

"This is a great process and as I've said over the last couple of days, we're going to keep working literally until the last vote is cast and counted," said Clinton.

According to polls, Clinton has lost ground to rival Bernie Sanders from neighboring Vermont, who is expected to win the Democratic vote

in New Hampshire.

For the Republicans, Marco Rubio was out early too, drumming up support at Manchester's Webster School, where voters were out in force from 6am.

Latest polls have Rubio sitting in third place among Republicans, behind front-runner Donald Trump and Senator Ted Cruz.

But all are aware that a long day of voting lies ahead, as candidates from both sides vie for supremacy in the Granite State.
