The Iowa Senate race for the open seat vacated by retiring Republican Joni Ernst remains tight, with prediction markets assigning Ashley Hinson a modest 54.5% implied probability compared to Josh Turek’s 45.5%. Recent polling averages show the contest essentially even or with a slight Turek edge, driven by voter concerns over tariffs, the Iran conflict, and economic pressures in a state Trump carried by double digits in 2024. The candidates’ first debate on October 7 highlighted sharp differences on immigration enforcement, bipartisan records, and responses to national policy, while independents have leaned toward Turek in several surveys. A second debate scheduled for October 13 and the start of early voting the following day could shift momentum, as could further data on farm economy conditions or candidate favorability trends ahead of the November 3 election.
