Trader consensus in the Iowa Republican gubernatorial primary market heavily favors U.S. Rep. Randy Feenstra at 56%, driven by his incumbency advantage, superior fundraising exceeding $1 million early, and top polling averages around 40-50% from Emerson and Fabrizio firms. Challenger Adam Steen holds 24.5% on grassroots momentum from conservative activism and rural endorsements, while state Rep. Zach Lahn trails at 16.5% amid name recognition from legislative service. Recent developments include Feenstra's January town halls boosting visibility and Steen's viral social media campaign criticizing federal overreach, shifting odds upward for both leaders; no major polls since February, with the June 2026 primary looming as next catalyst. Markets reflect uncertainty in early-cycle dynamics.
