For the first time in the 2016 presidential campaign, Bernie Sanders has a lead over Hillary Clinton. A new poll this week showed the Vermont senator overtaking Clinton in the critical first-in-the-nation primary state of New Hampshire.

Sanders tracks 7 points ahead of Clinton in a new Franklin Pierce University/Boston Herald survey of the Democratic primary there, taking 44 percent to her 37 percent.

It polled 442 likely Democratic primary voters in the Granite State last Friday through Monday and has a 4.7 percent margin of error.

It comes as Sanders continues to draw large crowds and Clinton faces more troubling questions about her private e-mail use as secretary of state.
