National Map >> Iowa Congressional Districts

Iowa has four congressional districts, of which three are held by Republicans. Three of the four districts look to be 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."
