The U.S. Supreme Court has allowed Arizona to enforce part of a 2022 law requiring proof of citizenship for state voter registration, but not for federal forms, affecting over 41,000 voters. Additionally, Arizona voters will decide on Prop 140 this November, an initiative to change the primary election system to an open format. Alaska's Supreme Court approved a ballot question for repealing the state's ranked choice voting system, which has been controversial since its narrow approval in 2020. In Wisconsin, the state Supreme Court is fast-tracking a case regarding the Green Party's ballot access, which could end up in the U.S. Supreme Court. Montana Democrats are suing to remove a Green Party candidate from the Senate ballot, citing procedural issues.
