The 27-year-old Brooklyn resident decided to support Claire Valdez, who was backed by Mayor Zohran Mamdani, over Antonio Reynoso, another progressive who was the choice of the Democratic establishment, because she had “a clear and more consistent stance.”

Valdez triumphed in her congressional primary, as did two other insurgent candidates endorsed by Mamdani, and Israel was a key issue in each of the races. Now the question for Democrats is how many more voters like Venkatesh are out there as the party charts its path toward the November midterms and the next presidential election.

The war in Gaza, which began during Joe Biden’s presidency and undermined Kamala Harris’ bid to replace him, remains an open wound, and how Democrats attempt to stitch it closed will help define their future. A step in any direction risks alienating pieces of the party’s unwieldy coalition at a time when it’s trying to unify around the mission of retaking control of Congress.

“The Israel question has become defining,” said Matt Bennett, who leads the centrist Democratic group Third Way and frequently criticizes progressives as jeopardizing outreach to independent voters. He said some in Mamdani’s camp have embraced “a new level of extremism,” warning that “Republicans are very good at weaponizing crazy ideas on the fringe against mainstream candidates.”

Mamdani has no such concerns as he tries to reshape the Democratic Party from the mayor’s office of the country’s largest city. He sharply criticized the American Israel Public Affairs Committee for defending what he calls “a status quo of immorality” in Gaza, and voters who celebrated his slate’s victories on Tuesday night chanted “Free Palestine.”

The mayor, meanwhile, argues that New York should shape Democrats’ search for their national identity in the coming years.

“When does the race for 2028 begin?” Mamdani asked last week on a stage with his slate of candidates. “It starts now.”

Israel-Palestine conflict animates Democrats’ left flank

Even for a party accustomed to searing debates between progressives and moderates, the schism over Israel has been blistering. Although the U.S. alliance with Israel once had bipartisan support, the ascendancy of Israel’s right wing led by Prime Minister Benjamin Netanyahu strained those ties over the years. Then the war in Gaza shredded them.

Biden was denounced as “Genocide Joe” by pro-Palestinian supporters, who shifted their attention to Harris once she replaced him as the Democratic nominee for president two years ago.

“She was trying to the right thing,” said Jamie Harrison, who led the Democratic National Committee at the time. “It was a hard and awkward place to be in.”

Harrison said the war in Gaza helped cost Harris the state of Michigan, which has a sizable Arab American population. However, he doubts that it was a defining national issue then or now.

“It’s one thing to be in New York. But I can tell you that most places, including where I am in South Carolina, it’s not what people are talking about,” he said. “They are concerned about affording gas and groceries and housing.”

Harrison expects Democrats to look for middle ground in the future, which includes “still supporting Israel’s sovereignty” while calling for “reducing U.S. aid to Israel and changing the nature of the relationship.”

One primary victor blasted the ‘hug Bibi’ strategy

Finding middle ground has been difficult so far, as demonstrated by the primary in New York’s 10th congressional district.

Brad Lander, the former city comptroller backed by Mamdani, successfully challenged U.S. Rep. Dan Goldman in the race.

Both candidates are Jewish, and both have criticized the Israeli government. But Lander says the war in Gaza is a genocide, and Goldman does not.

“Our party needs to admit that Joe Biden’s ‘hug Bibi’ strategy was a catastrophic mistake,” Lander said in his primary victory speech. He added, “We cannot keep paying for Netanyahu’s wars with our tax dollars. Democratic voters are saying this, loud and clear.”

Ari Rassouli, a voter in the district, said the incumbent’s views on Israel were “one of the many reasons that I didn’t like Dan Goldman.”

Describing the war as a genocide, she said “a candidate that is in support of that has no place in our democracy at all.”

While talking to reporters on Tuesday, Lander acknowledged that Israel was among the top issues along with affordability and immigration.

“I like talking to Jewish voters who feel anxiety about the times we live in and say, ‘I have these values, I want to treat everyone like they’re equal and with dignity and created in God’s image. How do we navigate the times we’re in?’” he said.

He added with a smile, “Those are probably the longest conversations at the polls.” ___
