"I'm not going to stop saying what I'm saying," he said on ABC News' "Good Morning America" Tuesday morning. "My whole campaign is built on this idea that the country is headed in the wrong direction as a result of the deliberate part of this president to put in place policies that change the relationship of government to our economy and America's role in the world."
"We look forward to continuing to say that," he added.
In the lead up to Tuesday's New Hampshire primary, Rubio has been criticized for repeating lines from his stump speech again and again while criticizing President Barack Obama.
New Jersey Gov. Chris Christie (R) even called him out during the last GOP debate for delivering the same "memorized, 25-second response." Rubio used a canned line three separate times in that debate, saying, "Obama knows what he's doing" even after Christie's attack.
He then lamented the difficulty in instilling proper values in children in the 21st century twice in a row during a campaign event on Monday.
Rubio is expected to finish second in the New Hampshire primary with about 15 percent support, according to HuffPost Pollster, which averages the state's latest opinion polls.
He acknowledged Tuesday that he was not in the lead, saying that "Trump is a clear frontrunner." Rubio also noted that "you've got some people who haven't campaigned anywhere else but here."
"It's a pretty unusual setup," he said. "But we feel really good. I have more national security experience and foreign policy experience than anyone else than anyone on the Republican side, by far."
