DES MOINES, IOWA  –  Republican Zach Nunn has upset Congresswoman Cindy Axne to win election to Congress representing Iowa’s third district, the Associated Press is reporting. The call of the race was delayed by reporting issues in two counties.

Nunn has served as an Iowa state lawmaker since 2015. Axne was seeking her third term in Congress. The victory ensures a Republican sweep of Iowa’s four congressional districts.
