Over 90% of the bills that passed both chambers in the second regular session of the 104th Illinois General Assembly were sponsored by Democrats, reflecting one-party dominance created by partisan gerrymandering.
In that second session, nearly 3,100 bills were filed. Almost 400 passed both chambers — with only 34 of those introduced by Republicans. That’s fewer than 10% of the bills sent to Gov. J.B. Pritzker.
Why does that matter? The Illinois Democratic supermajority is freezing out its Republican peers via partisan gerrymandering of legislative districts.
All bills filed in the General Assembly go to the House Rules Committee or Senate Assignments Committee before being referred to an appropriate subject committee. In practice, the rules and assignment committees are often where bills go to die.
This is particularly true for bills introduced by Republican lawmakers. Nearly half of Republican-sponsored bills in the 2026 regular session were never referred to a subject committee, compared with 15% of Democrat-sponsored bills.
