No. New Illinois is a nonpartisan organization. We complain about politicians from both parties. It is likely that many Republicans support New Illinois because more of them live in the area that is disenfranchised.
We believe that our real foe is the legendary, systemic corruption in the Illinois state government. It has existed for decades under both parties and is bigger than any individual. Regardless of party, nobody benefits from a lack of representation, government corruption, and a state that is broke.
