Iowa Senate Race Heats Up: Hinson Backed by GOP as Ernst Retires in 2026 Midterms

Iowa voters will head to the polls on November 3, 2026, for a midterm election that features a wide-open U.S. Senate seat, all 435 House races nationwide, and a slate of gubernatorial contests. For Iowa, the marquee event is the race to replace retiring Sen. Joni Ernst, a contest that has already drawn significant Republican and Democratic interest.

Who is running for Iowa's open Senate seat?

Sen. Joni Ernst's decision to retire has set off a competitive battle for her seat. On the Republican side, Rep. Ashley Hinson has emerged as the party's endorsed candidate, bringing her congressional experience and conservative credentials to the race. Democrats have three contenders vying for their party's nomination: state Sen. Zach Wahls, state Rep. Josh Turek, and military veteran Nathan Sage.

Hinson's campaign is expected to focus on the issues that matter most to Iowans, including agricultural interests, energy independence, and parental involvement in education. Her record in the House has aligned closely with the conservative values that dominate Iowa politics, and she has already secured key endorsements from state Republican leaders.

What other Senate races are drawing national attention?

Beyond Iowa, several high-profile Senate races are shaping up across the country. In Kentucky, Senate Minority Leader Mitch McConnell is ending his 40-year career, creating a crowded open-seat contest with six Republicans and eight Democrats competing. Alabama Sen. Tommy Tuberville is leaving the Senate to run for governor, while Sens. Marsha Blackburn of Tennessee and Michael Bennet of Colorado are also pursuing gubernatorial bids.

North Carolina's open seat, vacated by Sen. Thom Tillis, has attracted former Gov. Roy Cooper on the Democratic side, while former Republican National Committee Chairman Michael Whatley and Michele Morrow are competing for the GOP nomination. Ohio features a rematch between former Sen. Sherrod Brown and incumbent Sen. Jon Husted, and Georgia's Democratic Sen. Jon Ossoff is seeking another term.

In Texas, Sen. John Cornyn faces a primary challenge from Attorney General Ken Paxton and Rep. Wesley Hunt, while Maine's Susan Collins awaits a Democratic challenger. Michigan's open seat, left by retiring Sen. Gary Peters, has drawn Republican Mike Rogers and Democrats Abdul El-Sayed, Haley Stevens, and Mallory McMorrow.

Which House races should Iowans watch?

All 435 House seats are on the ballot, and several races are drawing attention for their competitiveness. In Iowa, the focus remains on the Senate race, but House contests in other states could shift the balance of power. Arizona's 6th District, where Republican Rep. Juan Ciscomani faces Democratic challengers, and New Mexico's 2nd District, where Democratic Rep. Gabriel Vasquez is challenged by Republican Greg Cunningham, are both closely watched.

Colorado's 8th District has a Republican primary challenge against Rep. Gabe Evans, and Michigan features multiple competitive races, including an open seat in District 10 as Rep. John James runs for governor. Eleven House members are running for governor, and 18 are retiring, including former Speaker Nancy Pelosi.

What does this mean for Iowa voters?

The 2026 midterms offer Iowa voters a chance to shape the direction of the state and the nation. With a Senate seat open and control of Congress at stake, the November 3 election will be a pivotal moment for conservative priorities like limited government, border security, and economic growth. Voters should pay close attention to candidate positions on these issues as the campaign season unfolds.
