'We're headed for a long fight': Elizabeth Warren vows to stay in race as she drops to fourth in New Hampshire

Senator and presidential hopeful tells supporters: 'Our best chance of beating Donald Trump is with a candidate that will work'

Elizabeth Warren has insisted she would stay in the race for the White House despite a weak showing in New Hampshire’s first-in-the-nation primary, telling her supporters in a speech on Tuesday night: “I am here to get big things done.”

“Our best chance of beating Donald Trump is with a candidate that will work,” she said, “a candidate who can build a campaign to unite our party and a candidate who can build a movement who is ready to take on corruption and win.”

Ms Warren then referenced Amy Klobuchar, who appeared to place in third according to early results in New Hampshire’s primary.

“Amy and I are the only candidates in this race who are not either billionaires or supported by Super PACs,” she said.

The Massachusetts senator added: “Tonight, I am here to say thank you.”

The comments came as iresults showed Mr Sanders in first place, followed by Mr Buttigieg and Ms Klobuchar, respectively.

Both Mr Sanders’ and Ms Warren’s home states border New Hampshire, and the two candidates were seen as popular progressives to lead the state. But Ms Warren suffered a dip in polls as more moderate candidates like Mr Buttigieg and Ms Klobuchar had strong showings in Iowa’s caucus the week prior.

Still, she appeared hopeful for her campaign on Tuesday night, telling supporters: "We're headed for a long fight."

Ms Warren's campaign also released a memo to staffers that was later obtained by multiple outlets on Tuesday afternoon, in which the campaign manager appeared to describe the senator as an underdog candidate who was in it for the long haul.

That memo claimed Mr Sanders faced a "ceiling" of support in the race that would prove true throughout the primary process, while Joe Biden, who appeared to place in fifth in New Hampshire, was on the verge of his campaign collapsing.
