2020 Political Endorsements

Sierra Club Illinois' tax exemption status - 501(c)(4) - allows us to make endorsements for candidates and ballot measures. Sierra Club Illinois makes its endorsements through a rigorous process that takes into account a candidate's environmental voting record, their answers to our questionnaire, and their electability. If you're excited about volunteering for one of our endorsed candidates' campaigns, fill out our interested volunteer form and tell us that you'd like to work on a local campaign! 

For 2020 congressional endorsements (U.S. House and Senate), click here.

This year, Sierra Club Illinois has endorsed the Fair Tax. We urge you to vote yes on this crucial ballot measure to fix our broken tax system and help fund our environmental agencies. Read more here.
