Cook County Board President Toni Preckwinkle, a seasoned politician who has led the county since 2010, is seeking a fifth term in the upcoming Democratic primary on March 17, 2026. Preckwinkle, 79, has been a pivotal figure in Cook County politics, overseeing significant initiatives such as the elimination of cash bail in Illinois and the reduction of medical debt for residents. Challenging her is Alderman Brendan Reilly, 56, who has represented Chicago's 42nd Ward since 2007. Reilly, a former president pro tempore of the Chicago City Council, is known for his moderate to conservative stance within the Democratic Party. His campaign focuses on fiscal responsibility and public safety, aiming to bring a fresh perspective to the county's leadership.
