County-level results in IA-03 from 2018 through 2024
Laura Belin created all of the tables enclosed below using certified results from the Iowa Secretary of State’s office. In all cases, counties are listed in descending order by total number of votes cast in that year’s Congressional race.
Throughout this period, Polk and Dallas counties accounted for about 75 percent of votes cast in Iowa’s third Congressional district. But the political map adopted in 2021 changed the shape of the district. Here’s the current configuration of Iowa’s U.S. House districts.
