Rob Sand holds a commanding lead in Iowa’s open 2026 gubernatorial race, backed by consistent polling averages showing him ahead by roughly six to nine points and strong fundraising that has produced nearly $18 million in cash on hand. As the sitting state auditor and the only Democrat elected statewide, Sand has built cross-party support through repeated 99-county town hall tours and emphasis on nonpartisan oversight of waste and fraud. Republican nominee Zach Lahn, a businessman who upset the Trump-endorsed primary favorite, trails in most surveys and trails substantially in available funds while facing the challenge of unifying a divided GOP base in a state that has trended Republican at the presidential level. Upcoming debates and late-cycle messaging on economic development and taxes remain the main variables that could still shift the race.
