2024 Iowa House Election Interactive Map
All US House seats to be contested in 2024
Iowa has four congressional districts, all of which are held by Republicans, after the party won District 3 in 2022. This marks the first time since after the 1994 election that a single party has controlled the entire delegation. It was the GOP in that last occurrence as well.
Overall, however, three of the districts are somewhat competitive; these were all won by Democrats as recently as 2018. In 2022, under slightly different boundaries after redistricting, these were all decided by an 8% margin or less.
