The Bottom Line

Illinois Democrats face a high-stakes primary Tuesday with divisions over Israel policy, race, and generational politics reshaping the party.

AI Summary

Illinois Democrats face a high-stakes primary Tuesday with over $35 million in TV spending, testing whether party divisions over Israel, race, and generational politics will reshape the party post-2024. AIPAC-affiliated groups have poured millions into House races, particularly the 9th District contest where their attacks on Evanston Mayor Daniel Biss may have inadvertently boosted progressive challenger Kat Abughazaleh, a Palestinian-American critic of Israel. Gov. JB Pritzker's aggressive backing of Lt. Gov. Juliana Stratton in the Senate race has angered prominent Black leaders who worry it could split the Black vote and help Rep. Raja Krishnamoorthi win, derailing a chance to elect a Black woman to Senate this cycle. Outside tech interests—pro-AI and pro-crypto groups combined spending over $15 million—are seeking allies in Congress to shape future regulation of those industries. Turnout patterns, particularly among Hispanic voters galvanized by immigration enforcement and in districts split over Israel policy, will signal whether Democratic fractures run deep heading into the general election.

What's Being Done

AIPAC-affiliated groups and tech industry interests (pro-AI and pro-crypto) have combined spending over $35 million in TV ads and political investments across House and Senate races.
