Redistricting

In Maine, both congressional and state legislative district boundaries are drawn by the state legislature. An advisory commission is also involved in the process. A two-thirds majority is required to approve new district maps, which are subject to veto by the governor.[12]

The composition of the 15-member advisory redistricting commission is as follows:[12]

  1. The majority and minority leaders of the Maine State Senate each select two commissioners.
  2. The majority and minority leaders of the Maine House of Representatives each appoint three commissioners.
  3. The chairs of the state's two major political parties (i.e., the Republican and Democratic parties) each appoint one member.
  4. The aforementioned 12 commissioners appoint two more members from the public, "with each party's representatives coordinating to choose one commissioner."
  5. The two public commissioners appoint one additional member.

This commission may make recommendations to the state legislature regarding redistricting, but the legislature is not bound to abide by the commission's recommendations. If the state legislature is unable to pass a redistricting plan, the responsibility falls to the Maine Supreme Court.[12]

State statutes require that congressional districts be compact and contiguous, In addition, state laws require that congressional districts "cross political subdivision lines as few times as possible."[12]

The Maine Constitution mandates that state legislative districts be "compact and contiguous, and that they cross political subdivision lines as few times as possible."[12] On September 29, 2021, Gov. Janet Mills (D) signed legislation enacting redrawn state legislative district boundaries. The Maine Apportionment Commission approved final maps and submitted them to the legislature on September 27, 2021. The Maine Senate unanimously approved both maps by a vote of 31-0. The Maine House of Representatives approved new district boundaries for the state Senate by a vote of 129-0 and new state House district boundaries by a vote of 119-10.[13] These maps took effect for Maine’s 2022 legislative elections.

The Maine Wire reported, "The legislature made no changes to the maps the Apportionment Commission submitted, but some legislators did express dissatisfaction with the way districts had been drawn."[14] Some lawmakers objected to changes made to the composition of their districts, such as Ben Collings (D). After the plans were approved, Collings said, "“I did my best to work with the [apportionment] committee and use the process to make those changes.” “Unfortunately that did not come together for the district I represent.”[13]
