Which process allows Arizonians to make changes to their state constitution?

The ballot initiative process in Arizona empowers citizens to propose amendments to the state constitution and to pass legislation directly through a vote. This mechanism allows residents to bypass the legislature if they feel strongly about a particular issue, giving them a direct voice in shaping their governance.

By gathering a certain number of signatures from registered voters, a proposed amendment can be placed on the ballot for public vote during an election. If the initiative garners enough support from the electorate, it becomes part of the state's constitution. This process reflects the democratic principle of allowing the populace to have a direct say in significant changes to their governing document, showcasing the role of citizen engagement and participation in Arizona's political landscape.

Other processes mentioned, like legislative amendments, constitutional conventions, and referenda initiated by the governor, have their own roles in governance, but they do not provide the same direct means for citizens to instigate constitutional changes themselves as the ballot initiative process does.
