Washington is one of 22 states that do not give direct control of redistricting to the state's legislature. The state's congressional districts are determined by a four-member Washington State Redistricting Commission that is appointed every ten years. Two members are appointed by both of the state's legislative branches, with the majority leader and minority leader from each selecting one person. The four appointed members then vote to appoint a fifth, non-partisan chairperson that cannot vote. The commission is disbanded once they have approved a redistricting plan. [6]
In 1981 Republicans attempted to gerrymander Tom Foley's fifth district by splitting Spokane (the district's main population center) into two districts, but this was vetoed by Governor John Spellman. [7] After they redrew districts in 1982, a federal court threw out the map for excessive population variation. New maps were drawn in 1983 by a five-member commission appointed by the legislature to avoid continued deadlock under a court-imposed deadline; [8] the legislature had historically often failed to redistrict. [7] In 1983, the voters approved a ballot measure to amend the state constitution to permanently establish a redistricting commission. The first commission created under the changes completed their work as part of the 1991 redistricting. [9]
Redistricting in the United States is the process of drawing electoral district boundaries. For the United States House of Representatives, and state legislatures, redistricting occurs after each ten-year census.
A long history exists of various individuals serving in the congressional delegations from the State of Texas to the United States House of Representatives and the United States Senate, with all of this occurring after Texas as a territory was annexed as a State in December 1865.
Since Montana became a U.S. state in 1889, it has sent congressional delegations to the United States Senate and the United States House of Representatives. Each state elects two senators to serve for six years. Before the Seventeenth Amendment took effect in 1913, senators were elected by the Montana State Legislature. Members of the House of Representatives are elected to two-year terms, one from Montana's at-large congressional district. Before becoming a state, the Territory of Montana elected a non-voting delegate at-large to Congress from 1864 to 1889.

The state has had as many as eight districts; the eighth district was eliminated on January 9, 1993 after results of the 1990 census, and the seventh district was eliminated in 2013, following results of the 2010 census, largely because of people moving interstate after Hurricane Katrina hit the state.
The U.S. state of Arizona, in common with the other U.S. states, must redraw its congressional and legislative districts every ten years to reflect changes in the state and national populations. Redistricting normally follows the completion of the United States census, which is carried out by the federal government the first year of every decade; the most recent census took place in 2020. Historically, Arizona's legislature had control over the redistricting process. However, Proposition 106, passed in 2000, delegated the power to draw congressional and legislative boundaries to a bipartisan independent commission. The Arizona Independent Redistricting Commission (AIRC) comprises two Democrats, two Republicans, and one independent chair. County and local redistricting, which normally takes place along the same timeline as congressional and legislative redistricting, is carried out by the individual county and local governments rather than the AIRC.
The Washington State Redistricting Commission is a decennial body charged with redrawing congressional and legislative districts in the state of Washington after each census. On November 8, 1983, Washington state passed the 74th amendment to its constitution via Senate Joint Resolution 103 to permanently establish the Redistricting Commission. Earlier that year the first commission redrew the state's congressional map after the previous one drawn by the legislature was ruled unconstitutional. Since after the 1990 census, a committee of four appointees of the majority and minority leaders of the House and Senate appoint a fifth member as non-voting chair, and meet to redistributes representative seats according to census results.
