Iowa's open Senate seat, vacated by retiring Republican Joni Ernst, pits Republican nominee Ashley Hinson against Democrat Josh Turek in a contest shaped by the state's recent Republican tilt and tight polling. Hinson, a three-term congresswoman endorsed by President Trump, secured her nomination decisively and holds a fundraising edge plus party organizational support in a state Trump carried by double digits in 2024. Turek, a state representative and Paralympic medalist, won his primary and has drawn national attention with endorsements including from former President Obama, while recent September surveys show the race within a few points amid voter focus on agricultural economics and tariffs. Forecasters largely rate the contest a toss-up, with trader consensus reflecting Hinson's structural advantages against Turek's competitive positioning ahead of the November 3 vote.
