Zach Wahls in Iowa's Democratic Senate primary, The Associated Press reported, and will now face off against Republican Rep. Ashley Hinson, who cruised to the GOP nomination.The Republican-controlled Senate seat in Iowa is a top target for Democrats, and the race is one of about a dozen crucial showdowns in this year's midterm elections that will determine whether Republicans successfully hold onto their slim majority in the chamber.THE MIDTERM RACES THAT COULD TIP THE BALANCE OF POWER IN THE SENATETurek, a moderate Democrat who flipped a GOP-held Iowa House seat in 2022, was backed by former Transportation Secretary Pete Buttigieg.Wahls, a progressive candidate who Republicans likened to New York City Mayor Zohran Mamdani, was endorsed by liberal champion Sen. Elizabeth Warren of Massachusetts.

Hinson, who in 2020 flipped a Democratic-held seat, is seen as a rising star in the party.Iowa was once a top battleground state that former President Barack Obama carried in his 2008 and 2012 White House victories. But the state has shifted to the right in recent election cycles with Trump carrying the state by nine points in 2016, eight points in 2020 and by 13 points in November 2024.Republicans hold both of the state's Senate seats — Ernst and longtime Sen. Chuck Grassley — and all four of Iowa's congressional districts, as well as all statewide offices except state auditor.But Democrats are energized heading into the midterms, when the GOP, as the party in power, will face traditional headwinds, a challenging political climate thanks to persistent inflation and sky-high gas prices due to what polls show is an unpopular war with Iran, as well as Trump's sinking approval ratings.And Iowa Democrats, in particular, are energized after flipping two GOP-held state Senate seats in special elections in 2025.The general election winner will succeed Ernst, a retired Army Reserve and Iowa National Guard officer who served in the Iraq War and was first elected to the Senate in 2014.Ernst grabbed plenty of national attention in that campaign with her "make 'em squeal" ads as she won the high-profile Senate election to succeed retiring longtime Democratic Sen.
