Outside Money and Sparse, Conflicting Polls Shape Illinois Democratic Senate Primary
On March 17, 2026 Illinois Democrats are choosing a successor to Sen. Dick Durbin in a primary dominated by Lt. Gov. Juliana Stratton and Rep. Raja Krishnamoorthi, with Rep. Robin Kelly consistently trailing—polling is sparse (about a dozen public polls) and conflicted, with some surveys showing Stratton narrowly ahead and others Krishnamoorthi up by double digits, raising concerns that a split Black vote or tactical promotion of Kelly could alter the outcome. The contest has been reshaped by massive outside spending—crypto‑funded super PACs (including roughly $10 million from Fairshake), AIPAC‑linked groups and other independent expenditures, plus millions from Gov. J.B. Pritzker to boost Stratton and a reported $30 million war chest for Krishnamoorthi—making the result a test of outside money and Pritzker’s political clout.
📌 Key Facts
- Illinois held its primary on March 17, 2026 to choose a successor to retiring Sen. Dick Durbin; the Democratic contest has coalesced around Lt. Gov. Juliana Stratton and Rep. Raja Krishnamoorthi, with Rep. Robin Kelly trailing, out of a field of ten Democrats and six Republicans.
- All three leading Democrats frame themselves as opposing Trump‑era deportation policies but differ sharply on immigration enforcement: Stratton says ICE should be abolished and some agents prosecuted; Kelly calls for dismantling ICE, Border Patrol and USCIS and rebuilding DHS; Krishnamoorthi says he will end Trump’s 'use of ICE,' refuse further ICE/CBP funding and supports stronger oversight and third‑party investigations into use of force.
- Gov. J.B. Pritzker has actively intervened — endorsing Stratton and directing millions from his personal war chest into a super PAC backing her (reported at least $5 million) — a move widely framed as a test of his influence as he is watched for possible 2028 national ambitions; Pritzker is running unopposed in the Democratic gubernatorial primary.
- Outside spending has been large and opaque: crypto‑aligned groups (Fairshake ~ $10 million opposing Stratton; Protect Progress hundreds of thousands) and AIPAC‑tied super PACs (more than $21 million across Illinois races) — plus AI‑industry PACs (Think Big ~$2.5 million) — have poured tens of millions into Illinois contests, reshaping the Senate primary dynamics.
- Fundraising makes Krishnamoorthi the financial frontrunner (reported war chest of about $30 million) while Stratton benefits from Pritzker’s outside spending; both camps have commissioned internal polls showing themselves competitive.
- Independent public polling has been relatively scarce and conflicting — only about 12 public polls since the start of 2026 — with some early/mid‑March surveys showing Stratton narrowly ahead and others showing Krishnamoorthi up by 10–11 points; an FM3 Research poll shortly before the primary found more than 10% of likely Democratic primary voters undecided, and Kelly has not led in cited public polls.
- Race and endorsements are a major factor: Black leaders worry Stratton and Kelly will split the Black vote; some outside groups backing Krishnamoorthi have actively promoted Kelly as a tactical move to peel support from Stratton; a circulated sample ballot claiming an endorsement from the late Rev. Jesse Jackson was disputed by his family as unauthorized, and Congressional Black Caucus chair Rep. Yvette Clarke publicly criticized Pritzker’s heavy‑handed role.
- On the ground, the primary was contested amid freezing temperatures and heavy early in‑person voting in Chicago, with voters citing issues like opposition to Trump, Social Security and public safety; observers view the outcome as both the choice of Durbin’s successor and a barometer of Pritzker’s political clout.
