2018 Michigan Proposal 2W
2018 Michigan Proposal 2

Michigan Proposal 18-2 was a ballot initiative approved by voters in Michigan as part of the 2018 United States elections. The proposal was created in preparation of the 2020 United States Census, to move control of redistricting from the state legislature to an independent commission. The commission consists of thirteen members selected randomly by the secretary of state: four affiliated with Democrats, four affiliated with Republicans, and five independents. Any Michigan voter can apply to be a commissioner, as long as they have not been, in the last six years, a politician or lobbyist. Proponents argued that Michigan's current districts are gerrymandered, giving an unfair advantage to one political party. Opponents argued that the process would give the secretary of state too much power over redistricting, and that the people on the commission would be unlikely to understand principles of redistricting. The proposal was approved with 61.28% of the vote.

Redistricting in ArizonaW
Redistricting in Arizona

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 in years that end in 0; the most recent Census took place in 2010. Historically, Arizona's legislature has 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.
