2020 Montana House Election Interactive Map

All US House seats to be contested in 2020
Montana has one at-large congressional district. It is one of 7 states with a single representative in the U.S. House. The seat is held by Republican Greg Gianforte, who is running for governor. Despite the lack of an incumbent, the seat is likely to stay in GOP control.

2020 may be the final election with this map, as Montana is expected to gain a district after the next Census. If that happens, redistricting will occur in 2021 to split the state into two districts. These will be first contested in the 2022 election.
