[3] She traditionally performed the best in Cook County, which was reflected by her victories in all ten congressional districts it is a part of.

[16] In order to be referred to voters, a proposed constitutional amendment must receive a vote of 60% approval in both chambers of the Illinois General Assembly.

[16] Advisory questions require a simple majority approval vote in each chamber of the Illinois General Assembly and the signature of the governor.

In Illinois, in order to be included on the ballot, an initiative must receive signatures of support equal in number to 8% of the turnout for the previous gubernatorial election.

Thus far, a single ballot measure (a legislatively referred constitutional amendment) has been scheduled for the November general election.

In the November 8, 2022 general election, Illinois voters voted on whether to ratify the proposed Right to Collective Bargaining Amendment.

[18] The amendment would, effectively, render any state or local "right-to-work" legislation (which would prohibit collective bargaining agreements that require union membership as a condition of employment) unconstitutional in Illinois.

[18] Prohibition on local-level right-to-work ordinances currently exists through both Illinois state law and federal legal precedence.

[19] In 2017, in a case concerning a 2015 local right-to-work ordinance adopted by the village of Lincolnshire, Illinois, Judge Matthew Kennelly issued a ruling in the United States District Court for the Northern District of Illinois that the National Labor Relations Act does not enable local governments to pass right-to-work laws.

[20][21] This was a ruling counter to a 2016 United States Court of Appeals for the Sixth Circuit decision on such laws.

[21] Kennelly's ruling was subsequently upheld the following year by the United States Court of Appeals for the Seventh Circuit in a unanimous decision.

[18] Currently, no state constitutions have a clause prohibiting right-to-work legislation (which ban collective bargaining agreements that require union membership as a condition of employment).
