Vice President Biden, who is reportedly on the verge of a decision about entering the Democratic race, draws 19 percent support in the poll.

Without Biden in the mix, both major declared candidates would see an uptick in support, but Sanders would lead Clinton by a slightly wider margin, 48 percent to 38 percent, according to the poll.

Sanders has led Clinton in the Granite State in a series of polls conducted since early August. Just one poll out of 11, released Friday from the Boston Globe/Suffolk University , found Clinton leading, though by just 2 points, 37 percent to 35 percent, following last week's first Democratic debate.

Clinton's favorability in the latest New Hampshire poll released Monday is at 74 percent, down 6 points since August, while Sanders's favorability has climbed 7 points since then to 83 percent.

The survey of 403 likely Democratic primary voters was conducted via landlines and cellphones in the days immediately after last week's debate, Oct. 14-17. It has a margin of error of 4.9 points.
