Iowa 2026 general election

News

AINews Summary

Ashley Hinson has secured the Republican nomination for Iowa’s 2026 Senate race. Democrats are still choosing between Zach Wahls and Josh Turek. The race is now moving toward the general election with the GOP field settled first. Hinson’s nomination removes Republican uncertainty and gives the GOP a defined candidate. The Democratic side is still unsettled, so the market may stay somewhat uncertain until that primary is decided.
