2020 Massachusetts House Election Interactive Map

All US House seats to be contested in 2020
Massachusetts has nine congressional districts, all of which are held by Democrats. None are seen as competitive in 2020. It is the state with both the largest number of districts under single party control and is tied with Tennessee as states with the most districts where not a single one is competitive.

Redistricting will occur in 2021 after the 2020 Census. While Massachusetts is expected to maintain its 9 congressional districts, expect some changes to the district boundaries that will be effective with the 2022 election.
