2018 Missouri House Election Interactive Map

All US House seats to be contested in 2018

Missouri has eight congressional districts, six of which are held by Republicans. All incumbents have at least three terms in the House and all are running again in 2018. Only the GOP-held, suburban St. Louis 2nd district appears to have some prospect of being competitive, and that would likely require a pretty strong Democratic wave.
