A ballot measure is a proposed law or amendment to existing laws that is submitted to voters for approval or rejection. These measures can address a wide range of issues, such as taxes, public services, or social policies. Voters typically encounter ballot measures during elections, where they can express their opinions through a simple yes or no vote. Ballot measures can be initiated by citizens, often through petitions, or by government officials. They serve as a way for the public to directly participate in the legislative process, allowing voters to have a say in important decisions that affect their communities and lives.
