Marco Rubio said on Special Report that he's feeling "very positive" about how his campaign is growing headed into the Iowa caucus. 

“I think people are starting to realize that If I’m our nominee, not only can I unite the Republican Party – which right now is quite divided. I can help grow the conservative movement, by taking our message to people that haven't voted for us before, people that are living the way I grew up.

"And also, that's why I think I can give us the best chance to beat Hillary Clinton."

Rubio touted his record as the junior U.S. senator for Florida, saying he's led efforts on bringing accountability to VA, removing a bailout fund from Obamacare, and imposing sanctions on Hezbollah.

"I'm proud of what we've done, but I'm even more excited about what we're going to do when I'm president."

Rubio said he's most qualified of all the Republicans to be commander-in-chief by a large margin.

"I have more foreign policy, national security and intelligence experience than everyone on that Republican debate stage combined."
