Sanders has eclipsed Clinton by a 44 to 37 percent margin, according to a new Franklin Pierce University/Boston Herald poll that was first reported by the Boston newspaper Tuesday evening.

The previous FPU/Herald poll taken in March had Sanders trailing Clinton 44 to 8.

Today's poll is the first to show Sanders, whose liberal policies are popular with the Democratic base, ahead of Clinton in New Hampshire.

And it comes as reports surfaced that Clinton will turn over her private email server that she used while leading the State Department to Justice Department officials.

Pollsters telephoned 442 likely Democratic voters in New Hampshire between Aug. 7 and Aug. 10. The poll has a margin of error of plus or minus 4.7 percentage points.
