Who are my U.S. senators in Iowa?
Right now, Iowa's two U.S. senators are: Chuck Grassley (R) — Iowa's senior senator, in office since 1981. His current term runs through January 2029. Joni Ernst (R) — in office since 2015. She announced she's not seeking a third term, so her seat is up in this year's election. Wikipedia For that open seat, Republican congresswoman Ashley Hinson and Democratic state representative Josh Turek are the nominees for their respective parties in the November 3, 2026 general election. Whoever wins will take office in January 2027, but Ernst remains the sitting senator until then. Wikipedia
