Illinois Primaries Highlight a Shifting Political Landscape
As Illinois voters head to the polls on Tuesday, March 17, 2026, the state’s primary elections are unfolding against a backdrop of increasing nationalization of local politics and the significant influence of outside spending. Candidates are navigating a complex terrain where traditional campaigning – meeting voters at local events like the South Side Irish St. Patrick’s Day Parade and touring churches – is increasingly overshadowed by the impact of large-scale financial contributions.
The Rise of Outside Money in Illinois Politics
The effects of the Citizens United ruling are particularly evident in this election cycle, with tens of millions of dollars flowing from special-interest groups into Illinois campaigns. These groups, often operating under generic names, represent diverse interests including pro-Israel advocacy, artificial intelligence development, cryptocurrency, and cloud data center industries. This influx of money is impacting races for both U.S. Senate and open U.S. House seats.
The U.S. Senate race is particularly competitive, with three Democrats – U.S. Reps. Raja Krishnamoorthi and Robin Kelly, and Lt. Gov. Juliana Stratton – vying for the nomination to succeed retiring Senator Dick Durbin. The financial landscape of this race is stark, with significant spending from super PACs supporting each candidate. For example, Fairshake, a pro-cryptocurrency PAC, has spent $9.9 million attacking Stratton, while Illinois Future PAC has channeled roughly $12.2 million to support her, largely funded by Governor JB Pritzker and his relatives.
Local Engagement Amidst National Forces
Despite the influx of outside money, candidates continue to engage in traditional campaigning methods. Krishnamoorthi greeted voters at the South Side Irish St. Patrick’s Day Parade, while Kelly rallied supporters in Chicago’s Northalsted neighborhood. Stratton focused on connecting with voters through events at churches and a veterans event in Hyde Park.
However, even these local efforts are being framed by the larger financial dynamics. Concerns about affordability, affordable housing, and cuts to federal programs are being discussed, but often overshadowed by debates over campaign funding. The influence of Governor Pritzker’s support for Stratton, for instance, has grow a central point of discussion.

The Republican Contests
On the Republican side, the Senate race features former Illinois GOP Chair Don Tracy, along with several other candidates. Tracy is focusing on appealing to dispirited conservative voters, emphasizing his political experience and business background. The race for the Republican gubernatorial nomination, challenging Governor Pritzker, includes Darren Bailey, Ted Dabrowski, Rick Heidner, and James Mendrick. This race has been characterized by a lack of significant financial investment compared to the Democratic contests.
