Rep. Ron Paul filed his candidacy via a representative Monday morning. Vice President Joe Biden will file paperwork for President Barack Obama on Thursday, the secretary of state's office said.
Huntsman arrived to fanfare in the afternoon, with supporters lining the halls outside the secretary of state's office. He handed over a folded check for $1,000 and signed the requisite paperwork.
He told members of the media at a press conference afterward that despite disappointing fund-raising numbers made public over the weekend, Huntsman felt optimistic about his chances in the nation's first primary.
"This is a state where conventional wisdom is always upended by candidates with good ideas and a vision for this country, a state where citizens take their first in the nation responsibility exceedingly seriously," he said.
Huntsman will campaign in New Hampshire Tuesday after announcing he would boycott events in Nevada. Nevada's GOP moved up its caucus date, which could in turn push New Hampshire's primary date into early- or mid-December.
Huntsman has pinned his presidential hopes on winning the state of New Hampshire.
