The open Iowa Senate race to succeed retiring Republican Joni Ernst remains closely contested, with trader consensus reflecting Iowa’s Republican tilt from the 2024 presidential results alongside mixed recent polling. Ashley Hinson, the three-term Republican congresswoman, holds a modest edge in the Polymarket pricing after the first debate on October 7, where candidates clashed over healthcare costs, immigration enforcement, tariffs affecting farmers, and Hinson’s record on Iran-related measures. Josh Turek, the Democratic state representative and Paralympic athlete, has narrowed gaps in some surveys by emphasizing bipartisanship and economic pressures, though his legislative attendance drew scrutiny. The economy ranks as voters’ top issue in late polling, with both campaigns highlighting it ahead of the November 3 vote.
