What percentage of voters is required to pass a referendum in Arizona?

In Arizona, a referendum requires a simple majority of voters to pass. This means that more than half of the votes cast must be in favor of the measure for it to be approved. The use of a simple majority reflects a common standard in many democratic systems, allowing for a straightforward decision-making process among the electorate.

Other options represent thresholds that are typically reserved for more significant changes or constitutional amendments, which require a higher level of consensus among voters, but they do not apply to the standard process for passing a referendum in Arizona. The simple majority requirement facilitates more accessible legislative changes, as it does not necessitate extensive support or consensus, making it more feasible for issues to be resolved through direct democratic input.
