Clinton hits the ground early as New Hampshire voting begins
Hillary Clinton is vowing to "keep working until the last vote is cast and counted" as voting in the New Hampshire primary begins.
Ms Clinton is starting her day before 7am at a Manchester polling location. She shook hands and posed for photographs with a group of volunteers and supporters.
Polls show Ms Clinton trailing Vermont Senator Bernie Sanders in the nation's first presidential primary.
Ms Clinton narrowly defeated Mr Sanders in last week's Iowa caucuses.
Ms Clinton declined to predict the outcome to reporters, saying she's "looking for a great election".
Meanwhile, Donald Trump says his campaign is 45 million US dollars (£31m) under budget as he enters the second race of the presidential nomination process.
Speaking to MSNBC's Morning Joe as polls opened in New Hampshire, Mr Trump acknowledged that he has polled well in the Granite State - but urged people to go out and vote.
Mr Trump also addressed a possible third-party run by former New York City Mayor Michael Bloomberg, calling Mr Bloomberg his friend, but acknowledging some of his shortfalls as mayor with regard to property development.
Mr Trump has maintained a lead in most New Hampshire polls among his Republican contenders leading up to today's primary.
