Democratic state auditor Rob Sand holds a consistent polling edge in Iowa's open 2026 gubernatorial race against Republican nominee Zach Lahn, supporting the current trader consensus reflected in market pricing. Incumbent Republican Governor Kim Reynolds opted not to seek a third term, creating an open seat in a state that supported Donald Trump by double digits in 2024. Lahn secured the GOP nomination in a June primary upset over the Trump-endorsed frontrunner. Multiple surveys from June through early August, including an Emerson College poll, show Sand ahead by roughly five points among likely voters. Forecasters have adjusted ratings toward a Democratic lean or tilt based on these trends. The November 3 general election remains months away, leaving room for shifts from campaign developments or turnout patterns.
