It’s a Buttigi-Edge!

Pete Buttigieg has skyrocketed to the lead in New Hampshire Democratic presidential primary polling, a new survey out Wednesday reveals.

The South Bend, Indiana, mayor grabbed 25% of support of primary voters in the Saint Anselm College Poll — up 15 points from a previous survey in September. Elizabeth Warren and Joe Biden are tied for second at 15%, followed by Bernie Sanders with 9%.

The results are disappointing for Sanders, the senator from neighboring Vermont, who easily defeated Hillary Clinton in New Hampshire’s 2016 Democratic primary.

The survey also found Amy Klobuchar with the support of 6% of voters, Tom Steyer at 5%, Tulsi Gabbard and Cory Booker with 3% each, Andrew Yang with 2% and Kamala Harris at 1%.

The race is fluid, with only 36% of primary voters in the Granite State saying they are firm in their choice and 57% saying they could change their mind.

“Buttigieg’s bump is driven by the favorable impression he’s made on voters, with 76% having a favorable impression of him versus only 11% unfavorable,” said Neil Levesque, the executive director of Saint Anselm’s New Hampshire Institute of Politics.

“His net favorable of 65% easily bests the field, including Biden [31%] and Warren [39%].”

The poll queried 512 registered New Hampshire voters — including 255 who expressed interest in voting in the upcoming Democratic primary — from Nov. 13-18. The survey has a margin of error of 4.3 percentage points.

The New Hampshire primary is Feb. 11, the second voting state after the Feb. 3 Iowa caucuses — where the 37-year-old mayor of South Bend has gained significant ground in recent months.

Buttigieg scored 25% in the latest CNN/Des Moines Register poll of the Hawkeye State, giving him a 9-point lead over the field.

His top-tier competitors were bunched together, with Warren landing 16% in the poll while Biden and Sanders were tied with 15%.

That’s a gain of 16 percentage points from the 9% that Buttigieg had in that poll in September, while Warren dropped 6 points and Biden slipped 5 points.

Buttigieg’s campaign is heavily invested in Iowa and has more than 100 staffers and 20 offices across the state, among the most of any candidate.

His campaign has sought to build on that advantage with TV ads touting his military credentials, including his tour in Afghanistan as a naval intelligence officer.

His aides are betting that a strong finish in Iowa will help quell questions about whether the small-city mayor is ready for the big stage and persuade reluctant black voters to give him a second look.

African American voters — a key block in the Democratic primaries — still heavily favor Biden, the former vice president, despite his disappointing debate performances, polls show.
