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!
