The Vermont senator is the favorite of 60 percent of the Granite State's likely Democratic primary voters, compared to 33 percent for Clinton.
Sanders' support has grown by 10 points since early December when the same poll found that 50 percent of Democratic voters supported him over Clinton, who garnered 40 percent.
Over that same amount of time, more voters have indicated that they have made up their minds about who to support, with 52 percent saying they know who they will vote for, compared to just 36 percent in early December.
Sanders' lead among undeclared voters, who don't belong to either party and can vote in either primary, is especially significant.
Among such voters who indicated that they plan on voting in the Democratic primary, Sanders leads Clinton 70 percent to 25 percent.
When only taking into account registered Democratic voters, the margin for Sanders shrinks to nine points, 50 percent to Clinton’s 41 percent. However, in December, Clinton led among those voters 47 percent to 40 percent.
A majority of the voters surveyed — 57 percent — also said that Sanders would do better with the economy, while just 33 percent said the same for Clinton.
Ninety-one percent of the voters in Sanders' neighboring state say they have a favorable opinion of him, compared with just two percent who say the opposite. Sixty-five percent say they have a favorable impression of Clinton.
The majority of the poll was conducted before the last Democratic debate. It surveyed 927 voters from Jan. 13 to Jan. 18.
Of those sampled, 420 said they plan on voting in the Democratic primary. The poll’s margin of error was 4.8 percent.
