During a special, two-hour edition of The Kelly File, Megyn Kelly pressed Marco Rubio on if he plans to change his tactics in the 2016 campaign, as he has not won a single Republican primary or caucus so far.

"What are you going to change to get a different result?" Megyn asked.

Rubio said that he relishes the role of the underdog, because that's what America is all about.

He said that once the race begins to narrow, he believes more and more Republican voters will get behind his campaign.

"The question is whether you like being second," Megyn pressed. "Because if you don't change anything, what are the odds that that number is going to start changing for you?"

Rubio reiterated that he will not dramatically change his tactics.

"My argument is: I'm as conservative as anyone running in this race," Rubio said, saying he'd put his record of conservative solutions up against any of his competitors'.

"I can unify this party, I can grow this party, and I will win this election."
