Chris Christie: Filing in N.H. Among Big Moments in Presidential Campaign 1:24

CONCORD, N.H. — Ohio Gov. John Kasich and New Jersey Gov. Chris Christie filed for the crucial New Hampshire primary Friday.

Both Kasich and Christie have spent a considerable amount of time campaigning across New Hampshire. The primary is the first held in the nation.

After signing the "Notice to Voters," Christie spoke with reporters and downplayed being relegated to the undercard at next week’s Republican debate due to low national poll numbers.

"I’ve never had difficulty making an impression,” Christie said. “I’ll make an impression Tuesday night too just like I have in the first three debates.”

"I’m not a moaner or complainer about rules, they are what they are and I’ll play under them," he said.

Christie and Kasich were met by supporters as well as those pressuring the candidates on issues as they arrived at the state house to sign the paperwork.

As Kasich arrived, women from Planned Parenthood wore pink t-shirts and held signs with slogans like "Unlike Kasich, NH Supports Planned Parenthood.”

People from NextGen Climate waved signs around Christie that read "#50BY30," a reference to the group’s goal of the U.S. achieving 50 percent clean energy by 2030, a goal Christie is not signing on to.

When Kasich walked into Secretary of State Bill Gardner’s office to sign his paperwork, he declared, "New Hampshire should always be the first primary state."

The intimate process here is the "perfect way to pick a president," Kasich said. "I love it."

When Kasich signed the notice, his message was the state’s motto, "Live free or die!" Rick Perry used the same message when signed the sheet as he filed for the 2012 primary.

After signing his paperwork, Kasich told reporters that he is the candidate Democrats fear most.

"They worry about me more than anybody else in the race and they're going to do everything they can to pick at me and figure out if they can throw enough mud at me to stop me,” Kasich said. “But I got news for them: ain't going to work.”

Afterwards, Kasich met with a group of 4th-graders who were on a tour and offered some life advice.

"When you have big dreams, you follow your dreams, okay?" he told them, and continued with a lesson about bullying. "Make sure you don’t leave anybody out in your class. Don’t pick on people, because that really makes people feel badly. So I want you to make me a promise that nobody gets cut out. Everybody’s included, okay?"

As Christie came down to speak to the press, he called President Barack Obama's decision to reject the Keystone XL Pipeline "predictable."

“I wish he just would have been honest with everybody and done it a long time ago,” he said. “Why did he lie to the American people for so long that he was considering it?”

When asked how a potential endorsement from Mitt Romney would shake up the 2016 race, Christie said it would be an “important moment” because Romney is the “standard bearer of our party.”

Christie said he is “subtly courting” the endorsement. "Mitt Romney is not the kind guy that you heavily court for those of you who know him, you know it would make him uncomfortable to be heavily courted.”

This week was a roller coaster of up and downs for Christie, after a video went viral of him speaking about a friend who lost his life to drug addiction.

Christie’s passion in the clip on the issue of treating addiction led to praise from across the country, but then news dropped that he won’t quality for the next primetime debate.

Kasich and Christie are the sixth and seventh major candidates to file for the New Hampshire primary.

Martin O’Malley and Donald Trump filed on Wednesday, and Marco Rubio, Carly Fiorina, and Bernie Sanders filed their papers on Thursday.
