The WBUR New Hampshire primary poll of likely Democratic voters shows Vermont Sen. Bernie Sanders with a narrow edge over former Secretary of State Hillary Clinton, and Vice President Joe Biden climbing. Sanders is pulling in 35 percent support to Clinton's 31 percent. While the poll finds Biden in third at 14 percent.

Among Republican voters in New Hampshire, WBUR's first monthly poll finds Trump still comes out on top, but Carson is coming close behind. So, the question is: could the presidential election come down to a choice between Bernie Sanders, the progressive from Vermont, and Ben Carson, the socially conservative Republican?

It seems that political outsiders continue to dominate this early stage of the political season.
