With Iowa's June 2 primaries two weeks away, trader consensus prices Democrat Rob Sand—a popular state auditor facing no serious primary opposition—at a 65% implied probability to win the open gubernatorial race, while Republicans sit at 30.5%. Incumbent Gov. Kim Reynolds' 2025 decision not to seek reelection removed her strong advantage in this historically Republican state, and recent polls underscore the shift: GBAO's March survey showed Sand leading Rep. Randy Feenstra 50%-42% (57%-29% among independents), with Echelon Insights in early April at similar margins. Cook Political Report upgraded the contest to Toss-Up in April, citing competitiveness amid a crowded GOP primary featuring five candidates including Feenstra, Andrews, and Steen, potentially weakening the nominee through intra-party spending and attacks. Sand's high favorability and unified Democratic field drive the market's Democratic lean ahead of the general election.
