2020 Iowa House Election Interactive Map
All US House seats to be contested in 2020
Iowa has four congressional districts, of which three are held by Democrats, after that party gained two seats in 2018. All four districts look to be in play in 2020. Closely-contested battles here are not uncommon. Iowa has one of the most impartial processes in the nation for setting district borders. A non-partisan advisory commission is "not allowed to consider previous election results, voter registration, or even the addresses of incumbent members of Congress. No politician…is allowed to weigh in, or get a sneak preview."
Redistricting will occur in 2021 after the 2020 Census. While Iowa is expected to maintain its 4 congressional districts, expect some changes to the district boundaries that will be effective with the 2022 election.
