2018 Maryland House Election Interactive Map

All US House seats to be contested in 2018

Maryland has eight congressional districts, all but one held by Democrats. The Republican-held district encompasses the entire Eastern Shore and is the largest one, by land area, in the state. The only incumbent not running is Rep. John Delaney, who was the first to announce his candidacy for the 2020 presidential election. That seat, as well as the others, are seen as safe for the controlling party.
