GOP Rep. Ashley Hinson will win Tuesday's Republican primary for Iowa's Senate seat, CBS News projects.
Hinson is vying to replace GOP Sen. Joni Ernst, who opted not to seek reelection. Republicans quickly lined up behind Hinson, who's represented Iowa in the House since 2021 and is endorsed by President Trump, making her the de facto GOP nominee heading into the primary. Hinson, 42, was projected to defeat former state Sen. Jim Carlin on Tuesday.
Democrats Josh Turek and Zach Wahls are competing for the Democratic nomination.
In a state that hasn't elected a Democrat to the Senate since 2008, Democrats face an uphill battle on paper. But the party has been increasingly bullish about their chances in recent months amid frustration with the cost of living.
