Races, candidates and ratings reflect public reporting as of June 2026; Michigan's Democratic candidate is decided at its August primary. Where a row has a source tag, it's that candidate's own stated position; where it says “Unverified,” we're showing the party's general stance as a placeholder until we confirm theirs. This tool is non-partisan and isn't tied to any campaign or party. Always double-check with official sources before you vote.
