U.S. Sen. Elizabeth Warren’s unfavorable ratings among women in the Granite State have ballooned by five points since she accused rival U.S. Sen. Bernie Sanders of saying a woman can’t win the White House, a new poll shows.

Warren has also lost support from both male and female voters in New Hampshire despite a new campaign push focusing on the Bay State senator’s electability and female electability in general, Monday’s Franklin Pierce University-Boston Herald-NBC 10 poll shows.

“Can we just address it right here? Women win,” Warren said at a 300-person rally in Davenport, Iowa, Sunday. “Women candidates have been outperforming men candidates — since Donald Trump was elected — in competitive elections.”

Warren’s “Women Win,” stump speech follows her bitter clash with progressive frenemy Sanders, who she claims told her that a woman can’t get elected president. The issue boiled over following a Jan. 14 debate when Warren refused to shake Sanders’ hand and said she believed Sanders called her a liar on television.

“So far, the polling doesn’t seem to indicate that worked very well for her,” said Brian Schaffner, a political science professor at Tufts University who specializes in public opinion and political campaigns.

According to a Jan. 13 FPU, Herald, NBC10 poll, 12% of Granite State female respondents had an unfavorable view of Warren. That number jumped to 17% in Monday’s poll, conducted between Jan. 23-26.

The poll puts Sanders in the lead with 29% of the vote, former Vice President Joe Biden follows with 22%, and Warren has 16% of the vote, according to the poll of 736 likely New Hampshire voters.

Warren is also struggling with male voters, with 11% of men in the poll backing her and 18% of women. Sanders has picked up a majority of male supporters — with 34% of men polled backing him and 26% of women.

But the Vermont senator’s unfavorable ratings have also increased since his clash with Warren, with 19% of women viewing him unfavorably in Monday’s poll. That’s a four-point increase since Jan. 13 poll that showed 15% of women viewed him unfavorably.

“Sanders does have some pretty fundamental weaknesses,” said Matt Dallek, a political science professor from the University of Southern California. “This shows that he does have a problem with women, and if Democrats truly want to find someone who can defeat Trump they’re going to need women.”

Much can change depending on the outcome of the Feb. 3 caucuses, said Schaffner, especially with 9% of New Hampshire voters still undecided, according to the poll.

“You have a lot of people who haven’t really decided yet. The dynamics of this race are still wide open,” said Schaffner.
