Redistricting

2020-2021

See also: Redistricting in New Jersey after the 2020 census

The New Jersey Congressional Redistricting Commission enacted a new congressional map on December 22, 2021.[11] This map took effect for New Jersey's 2022 congressional elections. The commission voted 7-6 to approve the Democratic map proposal, with all six Democratic members and the tiebreaker, former New Jersey Supreme Court Judge John Wallace voting to approve. All six Republican members of the commission voted against the map.

How does redistricting in New Jersey work? In New Jersey, congressional and state legislative district boundaries are drawn by two distinct politician commissions. The congressional redistricting commission comprises the following 13 members:[12]

  1. The majority and minority leaders of each chamber of the New Jersey State Legislature appoint two commissioners a piece (for a total of eight members).
  2. The chairs of the state's two major political parties each appoint two members to the commission (for a total of four members). Commissioners appointed by the political parties cannot be members of Congress or congressional employees.
  3. The first 12 commissioners appoint the last member. This member cannot have held public office in the state within the previous five-year period. If the first 12 commissioners cannot agree on an appointment, they must submit two names to the New Jersey Supreme Court. The court must then appoint the final commissioner.

If the congressional redistricting commission fails to reach an agreement about a redistricting plan, it must submit two plans to the state Supreme Court, which must in turn select from those two plans a final map.[12]

The state legislative redistricting commission comprises 10 members. The chairs of the state's two major political parties each appoint five members to the commission. In the event that this commission is unable to reach an agreement about a redistricting plan, the state Supreme Court may appoint a tie-breaking member.[12]

State law requires that state legislative districts meet the following criteria:[12]

  1. Districts must be contiguous.
  2. Districts "must be as nearly compact as possible."
  3. Municipalities "must be kept intact, except where otherwise required by law."

There are no such requirements in place for congressional districts.[12]

FiveThirtyEight's September 2018 elasticity score for states and congressional districts measured "how sensitive it is to changes in the national political environment." This district's elasticity score was 0.92. This means that for every 1 point the national political mood moved toward a party, the district was expected to move 0.92 points toward that party.[19]
