The leading pro-Israel lobbying group has kept quiet on the race for an open Senate seat in Illinois while pouring its largest investments this cycle into the state’s high-profile House primaries, leaving observers to wonder whether it would really sit out the Senate contest.

But for the top of the ticket in Tuesday’s Democratic primary, more than two dozen donors to the American Israel Public Affairs Committee are quietly backing Lt. Gov. Juliana Stratton, The Intercept has found. 

At least 27 AIPAC donors have given to Stratton’s campaign to replace retiring Sen. Dick Durbin, D-Ill., according to an analysis of federal campaign data. A former AIPAC president, Lee Rosenberg, is on her finance committee.

While public opinion sours on AIPAC’s brand, the group is backing a multimillion-dollar ad campaign run through other committees with palatable names like “Elect Chicago Women” in at least four Democratic House primaries. Its donors, meanwhile, have been funneling money to its preferred Illinois House candidates. The group has kept an even lower profile in the Senate race, where it’s been less clear how, if at all, the pro-Israel lobby is engaging.

Neither of the top contenders for the safe Democratic seat have suggested they would champion the Palestinian cause if elected to the Senate. Both Stratton and Rep. Raja Krishnamoorthi, her leading opponent, have declined to call Israel’s destruction in Gaza a genocide or commit to stopping U.S. weapons transfers to Israel, and at least one of Stratton’s pro-Israel donors also gave to Krishnamoorthi’s campaign. AIPAC endorsed Krishnamoorthi, who has received more than $250,000 from the pro-Israel lobby during his decade in Congress, for his 2024 reelection.

Both are running to the right of Rep. Robin Kelly, a relatively progressive Illinois congresswoman currently in a distant third, but even she staked out a more critical position on Israel upon entering the race and has taken some pro-Israel money while in office, much of it from the centrist group J Street.

AIPAC donors have given more than $70,000 to Stratton’s campaign since August, according to filings with the Federal Election Commission — out of just over $4 million she’s raised in total. The 27 donors have collectively given just under $5 million to AIPAC, its super PAC United Democracy Project, and the group Democratic Majority for Israel, which has close ties to AIPAC. Only two of them live in Illinois.

Rosenberg, the former AIPAC president on Stratton’s finance committee, is a leading Democratic strategist in Illinois, longtime adviser to Gov. JB Pritzker, and former adviser to Barack Obama.

In response to questions from The Intercept, a Stratton campaign spokesperson said that AIPAC had not endorsed the lieutenant governor and was not spending in the Senate race. The spokesperson said Stratton has more than 28,000 individual donors and supports a two-state solution for peace between Israel and Palestine.

In the final days ahead of Tuesday’s primary, Stratton has begun to catch up in the polls to Krishnamoorthi, who has largely outperformed his Democratic opponents in fundraising and public opinion surveys. The two candidates’ allies and critics have pointed fingers over fundraising, accusing the other of drawing support from corporate donors.

Krishnamoorthi’s $30 million fundraising haul is supplied in part by a crypto PAC, donors to President Donald Trump, and Palantir’s chief technology officer, among others, the Chicago Tribune reported on Tuesday. Stratton, meanwhile, has said she’s not taking corporate PAC money and hit Krishnamoorthi’s campaign for accepting support from a “MAGA-backed crypto PAC,” but her opponents have also criticized her Senate campaign for still benefiting from corporate donors that fund PACs backing her.

Democrats in Illinois have criticized AIPAC’s efforts to elect pro-Israel Democrats in deep-blue seats in and around Chicago. Pritzker, one of Stratton’s top surrogates and funders (and her boss), is a former AIPAC donor who cut ties with the group and has since denounced it as a “pro-Trump organization” and “significantly MAGA-influenced.”

Pro-Israel spending “is a moral issue,” said former Rep. Marie Newman, an Illinois Democrat who was ousted from Congress in 2022 after pro-Israel groups spent against her. “AIPAC must be stopped if you believe in democracy.” 

Stratton, who took a trip to Israel in 2019 to meet with an opposition leader, as Politico reported, has been critical of Israeli Prime Minister Benjamin Netanyahu and Israel’s destruction in Gaza. She has not said whether she would support legislation blocking U.S. weapons to Israel. 

Criticizing Netanyahu is at odds with taking support from AIPAC and its donors, Newman said.

“AIPAC vigorously supports Netanyahu, a right-wing dictator, best friend to Trump and his authoritarian inhumane government,” Newman told The Intercept. “Israel’s right-wing government has dragged us into multiple unnecessary wars, helped ruin the US’ reputation in the world and is committing genocide.”

While Krishnamoorthi holds the advantage in polling and fundraising, it’s not clear who will win on Tuesday as dueling PACs fight it out in the final days of the race. Another group that has run ads in support of Krishnamoorthi recently launched ads backing Kelly in an apparent effort to peel votes away from Stratton. Kelly, who has raised $3 million, has struggled to keep pace in the polls with Krishnamoorthi and Stratton, and their backers have labeled her a spoiler.

Kelly’s campaign argues that she’s the most principled of the three candidates, particularly on Israel and Gaza.

“Robin pledged not to accept contributions from AIPAC after deciding to sign onto the Block the Bombs bill and meeting with doctors who volunteered on the front lines in Gaza,” her campaign spokesperson Joe Bowen told The Intercept. “She is the only candidate who has pledged not to take their money, the only candidate to support Block the Bombs and the only candidate to call the genocide in Gaza what it is.”

Kelly, who has hit both Krishnamoorthi and Stratton for stopping short of calling Israel’s destruction in Gaza a genocide, adopted that stance shortly before she launched her Senate campaign. Previously endorsed by J Street, she received $14,000 from AIPAC in 2025 and took an AIPAC trip to Israel in 2016. Kelly, now the only major candidate in the race to reject AIPAC support, has said the contributions were from individual donors who gave through AIPAC’s portal.
