And the Democratic presidential nomination race just got a bit more interesting. At least in Iowa.
In a new Quinnipiac University poll, Sen. Bernie Sanders comes out on top with 49 percent of likely Iowa caucus voters choosing him over former Secretary of State Hillary Clinton. It's the first time he's led there since September.
Likely voters said Sanders could handle the economy and climate change better than Clinton could. And when it comes to trustworthiness, Sanders gets a 92 percent to Clinton's 69 percent. But when it comes to terrorism, foreign policy and health care, respondents chose Clinton.

"If that's the kind of revolution he's talking about, I am worried folks," Clinton told a crowd, critiquing Sanders' health care plan.
Clinton doesn't have a good track record with the Iowa caucus. In 2008, she took third in the state behind both then-Sen. Barack Obama and Sen. John Edwards. (Video via Hillary for America)
Sanders is leading in the first primary state, New Hampshire, too. Winning both would be big for Sanders who is still fighting off claims of his electability. But for the next two contests, South Carolina and Nevada, Clinton still holds double-digit leads in both. (Videos via Bernie 2016, Hillary for America)
