Chicago Progressive Partnership, a super PAC funded by AIPAC's United Democracy Project, spent over $1 million on ads attacking Palestinian-American progressive Kat Abughazaleh and boosting fellow progressive Bushra Amiwala in an Illinois congressional primary—a strategy designed to split left-wing votes. The FEC disclosure confirmed what had been widely suspected: the group was an anonymous front that allowed AIPAC to spend heavily on the race without publicly acknowledging its involvement or mentioning Israel, which is unusual given AIPAC's stated mission. This tactic failed to get AIPAC's preferred candidate elected but did help ensure the more progressive Abughazaleh placed second rather than winning outright.
