The Iowa Senate race for the open seat vacated by retiring Republican Joni Ernst remains a toss-up, with prediction markets assigning Republican Rep. Ashley Hinson a narrow 55% implied probability of victory over Democratic state Rep. Josh Turek at 44.5%. Recent polling shows the contest essentially tied or with small leads for either candidate within margins of error, including a Suffolk University survey giving Turek 48% to Hinson’s 44%. The Oct. 7 debate highlighted clashes over tariffs, the Iran conflict, immigration, bipartisanship records, and legislative attendance, with both sides emphasizing Iowa’s agricultural economy and voter concerns about costs. Early voting begins Oct. 14 ahead of the Nov. 3 election, and a second debate is scheduled for Oct. 13. Hinson benefits from the state’s recent Republican tilt, while Turek draws support from independents amid national economic dissatisfaction.
