Iowa's upcoming Senate election has emerged as a highly competitive race following the announcement of Senator Joni Ernst's retirement. Recent polling data reveals that the two leading candidates are closely matched, with Josh Turek maintaining a narrow advantage over Ashley Hinson as the race takes shape heading into the 2026 midterm cycle.

The contest is anticipated to rank among the most closely contested Senate races nationwide, reflecting significant electoral competition over this seat. The polling results underscore how competitive Iowa's Senate landscape has become as candidates position themselves to succeed Ernst, who was the first woman to serve as a U.S. senator from the state.
