Iowa Senate 2026: Ashley Hinson vs Josh Turek in America's Tightest Toss-Up

Iowa was not supposed to decide anything. Donald Trump carried the state by 13.2 points in 2024, no Democrat has won a United States Senate election there since 2008, and the seat itself only came open because the Republican incumbent, Joni Ernst, chose to retire. Yet on the eve of the vote, the race to replace her is the closest Senate contest in America: a Republican congresswoman who has never trailed in the betting markets, against a Democratic state legislator who has never trailed in the final week's best-known polls, separated by less than the margin of error in almost everything that measures them.

The candidates are Ashley Hinson, a Republican who represents Iowa's 2nd Congressional District and spent her earlier career as a television journalist, and Josh Turek, a Democratic state representative and two-time Paralympic gold medallist in wheelchair basketball. Libertarian Thomas Laehn is also on the ballot, drawing 1 to 7 percent in recent surveys. The contest matters beyond Iowa because control of the Senate may turn on seats exactly like this one: the Democrats need a net gain of four to reach 51, and Iowa is one of the few Republican-held seats where they have a genuine chance.

The polling picture is a genuine split, not a trend that one side can cherry-pick away. RealClearPolling's average through November 1 puts Hinson ahead by 0.3 points, 46.8 to 46.5. The New York Times/Siena poll of 705 likely voters, conducted October 26 to November 1, puts Turek ahead by one point, 48 to 47. YouGov's survey of 2,020 likely voters, conducted October 26 to 29, also puts Turek ahead by one, 50 to 49. A Republican-leaning firm, co/efficient, puts Hinson ahead by two, 48 to 46, in a survey of 1,020 likely voters on October 28. Every one of those leads sits inside its survey's margin of error. Nate Silver's forecast splits the difference in the other direction, giving Turek 47.3 percent to Hinson's 46.5. The Cook Political Report rates the race a toss-up, as does Sabato's Crystal Ball.

Two other signals point in opposite directions, which is why this race resists a clean call. On Sunday, President Trump held a rally in Dubuque and told the crowd that voters would elect Hinson to the Senate, yet Kalshi's market for the seat moved the other way that day: Hinson's implied chance fell four points in 24 hours to 52 percent, a new low for a candidate who has led the market all campaign. Meanwhile about 432,000 Iowans had already cast early ballots, 47 percent of them Democrats and 34 percent Republicans according to TargetSmart data reported by NBC News, a composition running more Democratic than in 2024. Early-vote composition is not a result, though: it says who voted first, not who will win, and in a state that leans Republican by six points on the Cook Partisan Voting Index, the Election Day vote has historically been the larger, redder wave.

What a result either way would prove is why Iowa is worth watching, not merely close. A Hinson win would say Iowa's Republican fundamentals still hold even in a bad national year for the party. A Turek win would say something larger: that farm-state anger over tariffs and the cost of living has finally broken a Republican hold lasting eighteen years. Republican-aligned groups had committed $33 million to holding this seat by late October, which is itself a kind of polling: parties do not spend that much on seats they believe are safe.

My judgment is that Hinson holds on, narrowly. The late polls favouring Turek are real, but both leads are within their margins of error, the polling average still leans the other way by a fraction, and Iowa's fundamentals — a state Trump won by double digits, a Republican lean of six points, eighteen years without a Democratic Senate victory — are the kind of gravity that usually wins a tied race. The market agrees, pricing Hinson at 52 percent on Kalshi on November 2, though it moved four points toward Turek in a day, so that agreement is thinner than it looks. If Turek wins, it will not be a polling miss so much as a structural break: the night Iowa stopped behaving like Iowa.
