That was when Sen. Bernie Sanders argued that Israel used “disproportionate” force against Hamas terrorists in 2014 and Hillary Clinton replied that Hamas had erected a “terrorist haven.”

The two presidential contenders rocked New York politics as Sanders spoke openly about the plight of Palestinians in the Gaza Strip and ripped into Israel for excessively responding to Hamas’ steady stream of rocket attacks on Israel’s civilian population. Never before in New York could anyone recall such a left-wing stance on Israel being articulated during a presidential campaign.

And it may happen again in the state’s race for governor.

The entry this month of actress Cynthia Nixon against incumbent Andrew Cuomo for the Democratic nomination raises the possibility of a faceoff over Israel and the Palestinians.

Nixon, who has been described as an impassioned liberal who would lead from the left, is challenging Cuomo’s progressive bona fides. Jewish voters might find it appealing that she has close ties to Manhattan’s Congregation Beit Simchat Torah and that Nixon, who is not Jewish, is raising her two eldest children from her first marriage as Jews.

But she will also have to defend to critics her decision in 2010 to sign a petition in support of Israeli artists who were refusing to perform in the Israeli West Bank settlement of Ariel.

That will make Israel a factor in the election for Jewish voters, predicted Hank Sheinkopf, a Democratic political consultant who is not aligned with either candidate.

“There will be a split between the more pro-Israel Jews and those on the left — and there are more pro-Israel Jews than not,” he said, a reference to studies showing explosive growth among the city’s Orthodox communities. “That is an indication of the changing nature of our community.”

Sheinkopf said that although Nixon “probably believes she will win the East Side and the West Side, she should rethink that because the Jews there are mostly Israel supporters and not boycotters. A boycott is a boycott and that is what she supported, whereas Cuomo has been against BDS and is pro-Israel.”

Cuomo in July 2016 signed the first-in-the-nation executive order directing state entities to divest all public funds from any organization or group that supports the Boycott, Divestment and Sanctions campaign against Israel.

Rabbi Jill Jacobs, executive director of T’ruah: The Rabbinic Call for Human Rights, said that as “someone who believes that being pro-Israel requires working to end the occupation and to create a two-state reality, I view signing a letter in support of Israeli artists who oppose BDS and who do not wish to perform in the occupied territories to be a pro-Israel action.”

“On the other hand,” said Jacobs, “supposedly anti-BDS regulations that collapse the difference between Israel and the occupied territories only play into the hands of those on the far left and right who wish to erase the difference between Israel within its internationally recognized boundaries and the occupied territories.”

She added in an email that Israel “should not be a major issue in the gubernatorial race, since New York state does not make its own foreign policy. Jews, like other New Yorkers, will consider a range of state-based social and economic issues when decided how to vote.”

Political activists say Cuomo continues to enjoy the support of the Jewish community, which could prove decisive in a close election because of the usually large Jewish voter turnout.

“Jews tend to support mainstream Democratic candidates,” said Larry Levy, a Long Island political expert and former Newsday political columnist. “They will go with those who are best known to them, whose views are considered moderate and who have shown the proper amount of deference to Israel.”

In addition, noted author Alan Skorski, “the Jewish community has always had a comfortable relationship with the Cuomo family.”

Cuomo’s late father, Mario, served three terms as New York’s governor from 1983 to 1994.

Cuomo is running for his third term as governor. In a January poll by Siena College, he had a strong favorability rating of 76 percent among Democrats — a figure that slipped to 53 percent last month perhaps because of the corruption trial of his former top aide, Joseph Percoco. A February Quinnipiac poll found that 47 percent of New York voters approved of his job performance.

Analysts believe Cuomo may be vulnerable from a credible opponent, pointing out that his 2014 Democratic primary challenger, Zephyr Teachout, a relatively unknown academic, amassed 34 percent of the vote.

But political consultant Bruce Gyory has been quoted as saying that Cuomo has strengthened his progressive credentials in the past four years, appeasing some left-wing critics with his ban on hydraulic fracturing.

A former executive director of the New York State Democratic Party, Basil Smikle Jr., observed that Cuomo “has a very progressive record.”

“He has been a strong supporter of Israel and the Jewish community, and he has the same advantage that most incumbents in New York will have. Ms. Nixon has to be able to articulate her reasons why she is running,” he said. “If she is running to the left of the governor, she has to convince voters why he is not progressive when he has a very progressive record.”

“That’s bad because she will have to spend some time building up her name recognition in a way that a celebrity candidate often doesn’t have to do,” Levy said. “But the good news is that she has a chance to define herself.”

Law professor Alan Dershowitz has criticized Nixon for signing the boycott petition, charging her with “bigotry” and noting that the petition was initiated by the far-left Jewish Voice for Peace. Among the 150 American actors, writers, directors and other artists who signed, he said, is Vanessa Redgrave, a vocal supporter of the Palestine Liberation Organization and a critic of Israel and “Zionist hoodlums.”

Others were actors Theodore Bikel and Mandy Patinkin, as well as playwright Tony Kushner.

“Jewish Voice for Peace has a benign name but a malignant agenda — ending Israel as the nation state of the Jewish people,” Dershowitz told The Jewish Week.

(The organization itself says it is in favor of any solution that supports the national rights of both Jews and Palestinians.)

“I don’t care if it’s Mandy Patinkin or anybody else who signed the petition circulated by this horrible anti-Zionist organization Jewish Voice for Peace,” Dershowitz said. “It shows either the worst judgment or the worst form of bigotry; it is no defense to say other Jews did it. … Does she not believe in Israel’s right to exist?”

Nixon did not respond to numerous phone calls and messages left with her representatives.

Dershowitz’s critical views of Nixon were echoed by Leon Goldenberg, a Democratic activist in Brooklyn.

“Anyone who supports BDS is a bigot,” he said. “If you only pick out one country to boycott and it is the Jewish state, then you are a bigot.”

Smikle said that having to explain her boycott position “will add to her burden to define herself against a very popular and progressive incumbent.”

Bob Liff, a Democratic activist from Manhattan whose children attended school with Nixon’s kids, described her as a “serious woman who was active in the integration fight in the school. She is smart. She is an open-minded woman.”

Liff dismissed Nixon’s signing of the Jewish Voice for Peace petition.

“I don’t buy that any of that reflects on her qualifications or lack thereof to be governor,” he said, adding that “to try to put some kind of anti-Semitic cast on the Nixon campaign is really a reach.”
