Hillary Clinton tried to use scare tactics with New Hampshire voters Friday, bolstering the benefits of Obamacare in her speech and claiming that any Republican president would kill those benefits.

"If the country elects a Republican president, then they will repeal the Affordable Care Act," Clinton told a crowd of about 850 people at Dartmouth University. "That is as certain as I can say."

Clinton told the crowd she was "thrilled" with the recent U.S. Supreme Court ruling that rejected a challenge to the act, and said she would always defend the law.

"Where there are glitches, we need to address those, but this is a fundamental issue of fairness and humanity," Clinton said.

Clinton also tried to hit the Republicans on economic issues, using her husband's record in office as her own.
