A pair of well-financed groups, whose origin is currently unknown, is set to begin running ads boosting moderate pro-Israel candidates in a series of open House seats in Chicago, each of whom is facing off against vocal anti-Israel opponents.

The ads — being run by newly formed super PACs Elect Chicago Women and Affordable Chicago Now — boost state Sen. Laura Fine, running in the 9th Congressional District, former Rep. Melissa Bean (D-IL), running in the 8th District and Cook County Commissioner Donna Miller, running in the 2nd District.

The ad buys for the two groups add up to millions of dollars across the three races.

Given that the groups were just launched, FEC filing policies will not require them to disclose their donors until close to Election Day. But the ads, which do not focus on Israel policy, are widely rumored to be connected to the United Democracy Project, the AIPAC-affiliated super PAC.

UDP did not immediately respond to a request for comment, and AIPAC has not made formal endorsements in any of the races in question. 

Fine has established herself as a supporter of Israel during her campaign, and Bean had a pro-Israel record in office. Miller’s public record on the issue is less established.

A spokesperson for Evanston, Ill. Mayor Daniel Biss, running in the 9th, declared that ads were being run by “a right-wing dark money super PAC” and that Fine “is being propped up by Trump supporters, AIPAC donors, and right-wing super PACs.”

Biss has called for a ban on offensive weapons transfers to Israel and far-left influencer Kat Abughazaleh, another leading candidate in the  race, has taken even stronger anti-Israel positions.

State Sen. Robert Peters, a 2nd District candidate who also strongly condemned Israel during the war in Gaza, posted a video earlier this week accusing “AIPAC and Trump donors” of “pouring cash” into Miller’s campaign, warning that “AIPAC and Trump allies” are “trying to buy this seat.”

One of Bean’s leading challengers in the 8th is Junaid Ahmed, who supports an arms embargo and an end to all military aid to Israel.

In several progressive-minded districts across the country, UDP has utilized similar pop-up groups and not disclosed its involvement until after Election Day.

The pro-Fine ad praises her record in office on issues like health insurance and gun control, as well as points to her support for a ban on Immigration and Customs Enforcement agents in Chicago. It calls her “the fighter we need to stop Donald Trump.”

ICE has become a major issue in the race, with both Biss and Abughazaleh attending anti-ICE demonstrations. Abughazaleh is under indictment for allegedly conspiring to injure ICE officers during a protest.

The pro-Bean ad highlights her support for the Affordable Care Act in her previous service in Congress, even though she “knew it might cost her an election,” and includes a photo of her with former President Barack Obama. It frames her new run for Congress as a continued effort to protect healthcare access from GOP attacks.

The pro-Miller ad highlights her work with Planned Parenthood and her work to protect pregnant mothers and combat domestic violence on the Cook County Commission. It also frames her as a fighter against President Donald Trump.

All three moderates — Fine, Miller and Bean — solidified their places as leading contenders in their respective races this week by leading in fundraising in the fourth quarter of 2025.

Fine also released an internal poll this week showing herself and Biss  tied for the lead in her race, with Abughazaleh in third and other candidates trailing.

Bean is seen as the front-runner in her race, given her established record. Miller, in spite of her strong fundraising, could face headwinds running against former Rep. Jesse Jackson, Jr. (D-IL), who has strong local and institutional support but struggled to raise money last quarter.
