Sabato's Crystal Ball moved Iowa's Senate race from Leans Republican to Toss-up on 22 September, for the open seat Joni Ernst is vacating1. The same day a Marist poll put Democratic state Representative Josh Turek ahead of Republican Representative Ashley Hinson 50-42 among registered voters, the first survey of the race to show the Democrat leading2.
Iowa's polls disagree sharply. Emerson College Polling had Hinson ahead 50-45 in a survey the same month, so the two readings sit 13 points apart on the margin. Sabato weighed the Marist result alongside other polls that still show Hinson ahead by four or five points. Its batch came against the backdrop of a president whose approval reached a record low in August.
Hinson holds Donald Trump's endorsement and a fundraising edge, and she was the NRSC's second-largest coordinated beneficiary in August. No Going Back PAC has not yet spent in the race, which leaves the party committee carrying the Republican effort in a seat Sabato now calls even.
Sabato also moved Iowa's 1st District, where Republican Mariannette Miller-Meeks faces Democrat Christina Bohannan, out of the toss-up column to Leans Democratic. Two Iowa races therefore moved towards Democrats in a single batch.
