Which office is responsible for overseeing elections in Arizona?

The Secretary of State is tasked with overseeing elections in Arizona, making this office crucial for ensuring the integrity and smooth operation of the electoral process. This responsibility includes managing election procedures, maintaining official election-related documents, and ensuring compliance with both state and federal election laws. The Secretary of State's role is foundational to the democratic process, as they facilitate the administration of elections, including voter registration and ballot counting.

In contrast, while the Attorney General focuses on legal matters and protections for the state, the Governor's role is primarily centered around executive functions and policy-making rather than direct election oversight. The State Treasurer manages the state's finances and budget, which does not encompass the administration of elections. Thus, the Secretary of State's designated responsibility distinguishes it as the correct answer in the context of overseeing elections in Arizona.
