The race for Iowa’s open Senate seat pits Republican U.S. Representative Ashley Hinson against Democrat state Representative Josh Turek, with recent polling showing a tight contest largely within the margin of error. Multiple surveys from late September and early October indicate Turek holding small edges among likely voters on issues such as cost of living and among independents and women, while Hinson maintains stronger support on immigration and among core Republican voters. Iowa’s Republican lean, reinforced by Donald Trump’s 2024 margin and his endorsement of Hinson, contributes to trader consensus favoring her at 56.5 percent. Two October debates and final voter turnout among suburban and unaffiliated blocs remain key variables ahead of the November 3 election.
