Redistricting

2020-2021

See also: Redistricting in Massachusetts after the 2020 census

Massachusetts Gov. Charlie Baker (R) signed the state’s new congressional maps into law on November 22, 2021. Both chambers of the legislature approved the new maps on November 17, 2021. The state House approved the plan by a vote of 151-8 with 127 Democrats, 23 Republicans, and one independent voting in favor and six Republicans and two Democrats voting against. The state Senate approved the new congressional maps 26-13, with 24 Democrats and two Republicans voting in favor and 12 Democrats and one Republican opposed. In the previous redistricting cycle, Massachusetts adopted its congressional map almost ten years ago to the day—on Nov. 21, 2011. This map took effect for Massachusetts’ 2022 congressional elections.

As Nik DeCosta-Klipa wrote at Boston.com after the legislature approved the maps, "unlike the partisan redistricting fights happening across much of the country, the map has been an argument among Democrats in reliably-blue Massachusetts. While the proposal does not dramatically alter the general contours of the state’s nine Democrat-held House districts...some of the tweaks around the edges have elicited vocal — to some, surprising — outcry." State Sen. Will Brownsberger (D), chair of the Special Joint Committee on Redistricting, said that he was unhappy that some members objected to the new maps. He said, "It’s always my goal to assure that every single senator is satisfied with the results of the redistricting process."

How does redistricting in Massachusetts work? In Massachusetts, congressional and state legislative district lines are drawn by the state legislature. The lines drawn by the state legislature are subject to veto by the governor.

State statutes require that state legislative district boundaries be contiguous and "reasonably preserve counties, towns, and cities intact, where otherwise possible." There are no such requirements in place for congressional districts.
