Rubio knocked Clinton, Democrats' presumed front-runner, as someone looking backwards.

"They're threatening to nominate someone now who wants to take us to the past — to an era that's gone and never coming back," Rubio said Friday night at a dinner with the Rockingham County Republican Committee. "The road we're on right now is a road that will rob us of the American dream."

The Florida senator also took aim at Obama, ribbing him for his recent focus on blue-collar workers.

"The extraordinary irony is the man who is now in the White House, and his party, actively campaigned six years ago on the promise that they would work for these people," he said. "They say 'Our new focus now is trying to help the people trying to make it.' What’s been your focus for the last six years?"

This is Rubio's first trip to New Hampshire in a year and a half. He made headlines in early-voting Iowa this week for endorsing Senate candidate Joni Ernst (R) in her crowded primary field.

Rubio took a dive in 2016 GOP primary polls after backing immigration reform. New Jersey Gov. Chris Christie's (R) dip has also opened the door for another establishment candidate to emerge.
