Declared candidates. Open seat: incumbent Kim Reynolds (R) declined to seek a third term. Primary held June 2, 2026. SURPRISE: businessman Zach Lahn upset Trump-aligned U.S. Rep. Randy Feenstra in the GOP primary; Democrat Rob Sand (state auditor) was unopposed. Libertarian Nicholas Gluba was disqualified from the general ballot. The field and its fundraising will keep updating as primaries settle and new FEC reports land.
