Sierra Club Wisconsin Chapter's 2026 Endorsements

The staff and volunteers of the Wisconsin Chapter are very proud to announce these endorsements. These candidates are committed to maintaining clean air, clean water and all the lands that make Wisconsin unique. We urge you, as Sierra Club members, to vote for and help elect new environmental leaders and re-elect proven elected leaders.


Governor

The Sierra Club Wisconsin Chapter enthusiastically endorses David Crowley for Governor. 

During his time in the legislature, David Crowley scored a 100% for his environmental voting record. As Milwaukee County Executive, he oversaw the adoption and implementation of the County’s Climate Action Plan. Tom Tiffany, on the other hand, has spent his entire political career selling Wisconsin’s natural resources off to the highest bidder.  He’s bought and paid for by some of the most polluting industries.

  • Mark Pocan, CD-2

State legislature

At the state level, our goal of creating pro-environment majorities in both houses of the Legislature is reflected in our endorsements of 10 State Senate and 56 Assembly candidates so far. Incumbent officials were judged based on their overall environmental voting record, public statements, and activities while in office. Challengers were evaluated based on their responses to questionnaires and interviews, environmental platforms, public service, and public statements.
