Recent polling in the open Iowa Senate race shows a tight contest between Republican Ashley Hinson and Democrat Josh Turek, with averages near 46% each and most forecasters rating it a toss-up ahead of the November 3 election. Hinson has gained a narrow edge in several late-October surveys, including InsiderAdvantage and co/efficient, after earlier polls favored Turek. Both candidates stress independence from their parties on key Iowa issues such as agriculture, rural healthcare, prescription costs, and border security, while heavy outside spending and fundraising continue in the final week. The state's Republican tilt from the 2024 presidential results and Hinson's House experience contribute to trader consensus favoring her at current levels, though small margins leave room for shifts from turnout or late developments.
