Democratic presidential candidate Elizabeth Warren took first place in an unofficial straw poll while also surging statewide in New Hampshire.

Warren took the top prize in the straw poll held at NH Progressive Summit, organized by Granite State Progress.

Warren grabbed 34.6 percent of the vote, according to Zandra Rick Hawkins, executive director of Granite State Progress. Bernie Sanders came in second at 24 percent, with Cory Booker of New Jersey and Tulsi Gabbard of Hawaii each grabbing six percent. Some 250 people took part in the summit, which took place last Saturday at Manchester Community College. 

Any “home field advantage” between leaders Warren and Sanders likely cancelled each other out, as both serve as US senators for states adjacent to New Hampshire: Warren for Massachusetts and Sanders for Vermont.

Meanwhile, a broader public opinion poll indicates Warren making real strides across first-in-the-nation-primary state New Hampshire.

Former vice president Joe Biden remains the front-runner for the Democratic nomination, with Sanders a solid second. But the CBS News/YouGov online survey also reveals what other polls the past six weeks have shown — an ongoing rise for Warren. 

Biden stands at 33 percent support in the survey, far ahead of the rest of the historically large field of nearly two dozen candidates. Sanders, who trounced opponent Hillary Clinton in the 2016 Democratic New Hampshire primary, is second at 20 percent.

Warren stands in third, at 17 percent, with South Bend, Indiana Mayor Pete Buttigieg at 10 percent, and Sen. Kamala Harris of California at 7 percent. 

Former Rep. Beto O’Rourke of Texas is at 4 percent, with Sen. Cory Booker of New Jersey at 3 percent. Everyone else registered at 1 percent or less.

Finally, Warren opened four field offices this week in New Hampshire, including one in Portsmouth.
