Who presides over the Arizona State Senate?

The presiding officer of the Arizona State Senate is the Vice President of the Senate. In this context, the term "Vice President of the Senate" refers to a specific role within the legislative body, distinct from the Vice President of the United States. This individual is typically elected by the Senate members and has the authority to lead debates, manage legislative procedures, and ensure that rules are followed during sessions. This role is crucial for maintaining order and facilitating discussion among Senators.

The choices that include the Governor, the Secretary of State, and the Speaker of the House do not hold this specific presiding role in the Senate. The Governor is the head of the executive branch and has separate powers and responsibilities. The Secretary of State has a different function concerning elections and maintaining official records, and the Speaker of the House presides over the Arizona House of Representatives, not the Senate. Therefore, the role of presiding over the Arizona State Senate clearly belongs to the Vice President of the Senate, making this the correct answer.
