2018 Iowa House Election Interactive Map
All US House seats to be contested in 2018
Iowa has four congressional districts, of which three are held by Republicans. Two of the four districts look to be highly competitive in 2018. 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."
