The Strategic Priorities for Sno-Isle Libraries include "building civic engagement" as a priority and "foster a literate and informed citizenry" as a core purpose. Those commitments include support for the election process. All community libraries, and Library on Wheels services, have voter registration materials on hand. During election cycles, voter guides are available. Many libraries have ballot drop boxes nearby. Libraries often work with community organizations to host candidate and issues forums.
The April 24, 2018 election included Sno-Isle Libraries operations levy, Darrington School District levy, and a merger question for Fire District 28 voters.
