2020 Maryland House Election Interactive Map

All US House seats to be contested in 2020

Maryland has eight congressional districts: six are held by Democrats, one by the GOP and one vacancy. The Republican-held district encompasses the entire Eastern Shore and is the largest one, by land area, in the state.

The vacant seat, previously held by the late Elijah Cummings, will be filled in a special election on April 28. The seat will almost certainly stay in Democratic hands; no competitive U.S. House races are expected here in November, 2020.

Redistricting will occur in 2021 after the 2020 Census. While Maryland is expected to maintain its 8 congressional districts, expect some changes to the district boundaries that will be effective with the 2022 election.
