Bernie Sanders now leads Hillary Clinton by 14 points in New Hampshire, according to the latest Monmouth University Poll of likely New Hampshire voters who are likely to vote in the first-in-the-nation primary in February.

Fifty-three percent of these voters choose Sanders, compared to 39 percent for Clinton. And the new poll shows that Clinton has also lost her edge over Sanders among registered Democrats, women and older voters. Sanders has now surpassed her with these voters, while holding onto his lead among registered independents, men and younger voters.

Under New Hampshire's modified primary system, undeclared voters may vote in either the Republican or Democratic primary, although voters who are members of one of the parties cannot vote in the other party's primary. Clinton (42 percent) is now losing Democrats to Sanders (50 percent), compared to two months ago, when she led Sanders 57 percent - 35 percent.

A Marist/Wall Street Journal/NBC poll out this week, however, showed a very different snapshot, with Clinton leading Sanders among voters who are Democrats by 18 points.
