Partisan control in 2024

Arizona was one of 10 divided governments where neither party had a state government trifecta at the start of 2024 legislative sessions. A state government trifecta occurs when one political party holds the governor's office, a majority in the state Senate, and a majority in the state House.

Arizona was also one of 21 state legislatures where neither party had a veto-proof supermajority in both chambers. Veto overrides occur when a legislature votes to reverse a veto issued by an executive such as a governor or the president. If one party has a majority in a state legislature that is large enough to override a gubernatorial veto without any votes from members of the minority party, it is called a veto-proof majority or, sometimes, a supermajority.

Legislatively referred constitutional amendments
In every state but Delaware, voter approval is required to enact a constitutional amendment. In each state, the legislature has a process for referring constitutional amendments before voters. In 18 states, initiated constitutional amendments can be put on the ballot through a signature petition drive. There are also many other types of statewide measures.
The methods by which the Arizona Constitution can be amended:
The Arizona Constitution provides for three methods of amending the Arizona Constitution—a citizen-initiated process, a legislative process, and a state constitutional convention. Arizona requires a simple majority to approve constitutional amendments. Arizona requires a 60% vote to pass ballot measures to approve taxes.
Initiative
- See also: Initiated constitutional amendment
Article 21, citizens have the power to initiate constitutional amendments in Arizona. An initiated constitutional amendment is a citizen-initiated ballot measure that amends a state's constitution. Eighteen (18) states allow citizens to initiate constitutional amendments.
In Arizona, the number of signatures required for an initiated constitutional amendment for the ballot is equal to 15 percent of votes cast for governor in the most recent gubernatorial election. Petitions can be circulated for up to 24 months. Signatures must be submitted four months prior to the election at which the measure is to appear. A simple majority is required for voter approval. Arizona requires a 60% vote to pass ballot measures to approve taxes.
Legislature
According to Article XVI, the state Legislature can refer constitutional amendments to the ballot for voters to decide. A simple majority vote is required during one legislative session for the Arizona State Legislature to place a constitutional amendment on the ballot. That amounts to a minimum of 31 votes in the Arizona House of Representatives and 16 votes in the Arizona State Senate, assuming no vacancies. Amendments do not require the governor's signature to be referred to the ballot.
Convention
According to Section 2 of Article XXI of the Arizona Constitution, the state legislature can only call for a convention if it is approved by the electorate in a statewide vote. Any amendments, revisions, or proposals of the Constitution require a simple majority vote by the electorate.
