The Libertarian Party is ballot-qualified in Cook County, Illinois, but the election officials think that only means the party can have a primary for Cook County Executive offices. On February 1, the party filed a federal lawsuit, arguing that it is also entitled to nominate candidates in its Cook County primary for County Commission. Here is the Complaint in Libertarian Party of Illinois v Yarbrough, n.d., 1:22cv-578.

The Libertarian Party is qualified in Cook County because in November 2020, it polled 6.7% for State’s Attorney of Cook County. The vote test in Illinois is 5%. The State’s Attorney 2020 race was between a Democrat, a Republican, and a Libertarian.
