Massachusetts incumbent and Israel critic Sen. Ed Markey, 80, is expected to handily fend off the more moderate 47-year-old Rep. Seth Moulton on Tuesday, in the state’s Democratic Senate primary.  

Although polls project that Markey, a progressive stalwart, will retain his seat, this race began as a neck-and-neck battle between the old and new guard. Yet in contrast to many recent primaries, the junior candidate in this case is the more centrist of the two.  

If current numbers hold, Markey could go from leading Moulton by just single digits two months ago, to trouncing him by 30 percentage points. The incumbent recently “opened a large lead,” with the University of New Hampshire’s Bay State Poll projecting a 63% to 28% victory. That’s a dramatic shift from June, when the survey estimated a 41% to 35% margin. Since then, according to Bay State, Moulton lost moderate support while Markey consolidated socialist and progressive backing. 

The University of Massachusetts Amherst offered similar predictions, placing Markey far ahead of his competitor, 60% to 32%. Emerson College Polling, meanwhile, showed a comparable lead for Markey, with the incumbent at 60% and Moulton at 33%.

“At the end of the day, one of the reasons for Moulton’s flame-out is that he had no case to make other than ‘I’m younger than Ed Markey,’” Jeff Robbins, a Boston-based attorney and former Senate investigative counsel, told the Jewish Telegraphic Agency.

“He wasn’t able to obscure that very well,” added Robbins, who also served as delegate to the United Nations Human Rights Commission under President Bill Clinton. He also began organizing rallies in support of Israel in 2012, during his time serving as chairman of the New England Board of the Anti-Defamation League.

Markey's long tenure in Congress

Markey began serving in the US House of Representatives 50 years ago, staying in that role until he was elected to the Senate in 2013. During his time in the House, he was a member of the Congressional Progressive Caucus, and in the Senate, he has voted for multiple resolutions aimed at cutting military aid and munitions sales to Israel.

Moulton, meanwhile, was born two years after Markey arrived on Capitol Hill. He has been serving in the US House since 2015 and has been critical of both the Democratic socialist agenda and the aging establishment, instead calling for “new energy, new ideas and leaders willing to put people over politics.”

He established the Serve America PAC in 2017 to support the campaigns of “military veterans, other service-driven candidates and next generation leaders” in the 2020 election cycle. The Boston Globe recently threw its support behind Moulton, calling for  “new vision and vigor” in “an aging, ailing and deeply unpopular Democratic Party.”

Yet a recent New York Times piece described Moulton as a “rebel without a cause,” who has “tried to drift where he thinks the political winds are blowing.” One such drift relates to his breakup with the American Israel Public Affairs Committee last October, when he announced that he would be “returning AIPAC donations and refusing to accept any donations or support from them.”

“In recent years AIPAC has aligned itself too closely with Prime Minister Netanyahu’s government,” Moulton said. “I’m a friend of Israel, but not of its current government.”

Track AIPAC, a group that documents political spending by pro-Israel lobbies, declared in response that “returning AIPAC’s blood money is better late than never.” The group demanded that Moulton call the war in Gaza a genocide and “stop writing blank checks” to Israel’s “tyrannical regime.”

Citing Federal Election Commission records, Track AIPAC found that pro-Israel PACs have spent about $101,500 on Moulton over his career — a relatively modest amount for a six-term congressman..

“It is clearly the safe thing to do, if you are running for a nomination in the Democratic Party, to aggressively distance yourself from Israel,” said Robbins.

He described the situation as “reflective of the reality that we have seen play out in spades over the last year,” in which Democratic candidates are “running for the hills about AIPAC and treating it as a boogeyman.”

Not only was Moulton’s decision insufficient to recruit AIPAC detractors to his campaign, but it also rattled many members of the Jewish community.

Distancing from the organized Jewish community is a political asset

Political scientist Samuel Abrams at the time described the decision as “the moment when an ambitious, mainstream Democrat concluded that distancing himself from the organized Jewish community is a political asset, not a liability.”

“In today’s Democratic ecosystem, the act of rejecting traditional Jewish institutions has become a badge of progressive credibility,” wrote Abrams, a senior fellow at the American Enterprise Institute, a center-right public policy think tank.

David Frum, a writer for The Atlantic and former speechwriter for President George W. Bush, suggested that Moulton was “opening the door *just a little* to anti-Jewish feeling,” In other words, Moulton would seek to win his primary by borrowing some “Mamdani energy,” Frum added, referring to the popular progressive mayor of New York City, Zohran Mamdani.

“If you want to have a prayer of being elected in a Democratic primary in this country, you had better be able to say, ‘I don’t take money from AIPAC. In fact, I never heard of it before,’” Robbins said.

But he stressed Moulton’s 30-point lag in the polls has nothing to do with Israel and everything to do with his opponent’s political shrewdness and refusal to allow anyone “to run to the left of him.”

Markey is not new to staving off a younger, center-left candidate. In 2020, at 74, he defeated the then-39-year-old Rep. Joe Kennedy III — marking the first loss for a Kennedy in a Massachusetts election, according to the Cook Political Report.

If the current polls prove accurate, Tuesday’s race could “mirror Markey’s successful ‘peak-late’ approach to winning in 2020,” Spencer Kimball, executive director of Emerson College Polling, said in a statement. “Younger voters appear more likely than older voters to support Markey, suggesting the campaign did not create the generational divide Moulton may have anticipated.”

As for Moulton’s relationship toward American Jews, he has historically denounced hate crimes and voted for resolutions on antisemitism. He also condemned Claudine Gay, former president of his alma mater, Harvard University, when she refused to say that calling for the genocide of Jews would violate the institution’s code of conduct.

Prior to his rejection of AIPAC money, Moulton’s stance on Israel was fairly balanced, with consistent messages on Israel’s right to defend itself, alongside criticisms of the country’s military operations in Gaza and calls for expansions of humanitarian aid.

Moulton’s objections have paled in comparison to Markey’s stance, which has ranged from demanding an end to arms sales to accusing the country of committing war crimes.

Markey did condemn Hamas’s Oct. 7, 2023 attack on Israel as terrorism, continuing to deplore the “dark day” as “heinous” in a statement two years later. But in that same statement, he also stressed that “more than 65,000 Palestinians have lost their lives in the brutality of the war in Gaza” and called “to stop the bloodshed.”

Markey's position switch on Israel

However, the senator didn’t always disapprove of Israel.

“For a long time he was right there with the Jewish community,” Barry Shrage, a professor of practice at Brandeis University and the longtime former president of the Combined Jewish Philanthropies of Greater Boston, told JTA.

In fact, Shrage and Robbins recalled in a recent Boston Herald column that during a November 2012 Hamas-Israel conflict, Markey asked them to help him organize a pro-Israel rally. The event, they wrote, was “full of appreciation for the fundamental fact that Israel is surrounded by non-state and state actors committed to annihilating it.”

But less than two years later, the tides had turned. After winning a 2013 special election to serve out the remainder of John Kerry’s Senate term, Markey then faced a general election in 2014 for a full Senate term. That summer, Hamas rockets rained down on Israel again, and the military responded to the attacks, as it did in November 2012.

Robbins said that when he and his colleagues decided to organize another rally in support of Israel at the time, he reached out to Markey.

“He ducks. He dodges. He doesn’t return the phone calls. He doesn’t return the emails,” Robbins recalled. “He had calculated correctly that it was not in his interest to have anything to do with Israel anymore.”

Shrage echoed these sentiments, observing that “it turned out to be at least from a political standpoint, if not from a moral standpoint, the right path.”

“It’s not a surprise that Markey is separating himself from Israel in every way that he can,” he added.

Looking toward the future, Shrage said that he had some hope for a turnaround on Israel in the Democratic party if, perhaps, a recent progressive primary winner lost against a Republican in the general election. Some possible examples could include Senate candidates Angie Nixon in Florida or Abdul El-Sayed in Michigan.

While Robbins agreed that a loss for El-Sayed could give a slight bump to Democratic supporters of Israel, he was pessimistic about the long-term ability to reverse the party’s increasing hostility toward the Jewish state.

“The only conceivable trigger for a walking back of this trend would be some massacre of Israelis so terrible that even the left would have to concede that Israel had the right to do what it did,” Robbins said.

“The problem with that is, it’s already occurred,” he added.
