Former Vice President Joe Biden has jumped to a small lead in the first-in-the nation New Hampshire primary, while Massachusetts Sen. Elizabeth Warren has slumped to third place, a new Franklin Pierce University-Boston Herald-NBC10Boston poll shows.

Biden now gets 26%, with Vermont Sen. Bernie Sanders in second place with 22%, and Warren trailing in third with 18%, according to the poll of 434 likely Democratic primary voters. South Bend Mayor Pete Buttigieg gets just 7% of the vote and former New York Mayor Mike Bloomberg is at 4%. Bloomberg is not on the ballot in New Hampshire, but voters can write in any candidate.

Twelve percent of the poll respondents said they were undecided heading into the last few weeks of the primary campaign.

The Democratic poll has a margin of error of 4.7 percent.

Warren appears to have suffered the most significant drop in support in the new poll.

In an October Franklin Pierce-Herald poll, she led the field with 25%, but voters now appear to be dropping off to other candidates or the undecided column.

On the Republican side, President Trump maintains a huge lead over his opponents, with 79% of the vote. Former Massachusetts Gov. William F. Weld and former Illinois Rep. Joe Walsh get 4% each.

Trump’s approval rating has dropped since October, and now sits at 76% with Republicans, according to the poll.

The poll was conducted Jan. 8-12.
