Illinois Candidates File for 2026 Primaries Amid Political Shifts

Candidates across Illinois have begun filing petitions to appear on the ballot for the March 17, 2026 primary elections, covering municipal, county, state, and federal offices. Incumbent Governor J.B. Pritzker filed for a potential third term, emphasizing his focus on education, health care, and economic growth, while Republican Darren Bailey's campaign is being managed by his running mate Aaron Del Mar due to a recent family tragedy. The filing period runs from October 27 to November 3, 2025, with a lottery system determining ballot positioning for early filers. Other notable candidates include those running to replace retiring U.S. Representatives and Senators, as well as county officials like Cook County Board President Toni Preckwinkle and her challenger Brendan Reilly. The filing process involves submitting nominating petitions, Statements of Candidacy, and economic interest disclosures, with primary elections set for March 17, 2026, and general elections on November 3, 2026. Both the Democratic and Republican parties are actively preparing for competitive races, with candidates and party leaders expressing varying strategies and optimism for upcoming contests.
