Illinois Overview

Redistricting Process: The state legislature and governor initially control congressional and state legislative redistricting in Illinois, and a back-up commission takes over should the legislature fail to meet certain deadlines. According to the state constitution, the legislature and governor are supposed to pass a redistricting plan through the normal bill process. However, the legislature has failed to meet the deadline every redistricting cycle since the current system was put in place in 1970. Redistricting power in Illinois then reverts to an eight-member commission consisting of one legislator and one member of the public appointed by the majority and minority leaders in each house of the state legislature. Since this commission has consisted of equal membership from each party, it has never been able to reach a compromise on a plan, necessitating the appointment of a tie-breaking chairperson. Under this process, the Illinois Supreme Court nominates one member from each party to be the chair, and the secretary of state selects a name from a hat to be the chairperson. Generally, this means that whichever party’s nominee is chosen from the hat will hold redistricting
power for that cycle. In 2011 Democrats control both houses of the Legislature and the Governor’s office, increasing the odds that, for the first time, the
backup commission will not be necessary. Illinois is the largest state where Democrats control the entire redistricting process.
