Who assumes the office of governor if the current governor resigns or is removed from office until a special election is held?

The correct answer is the Lieutenant Governor. In Arizona, if the governor resigns, is removed from office, or becomes unable to perform the duties of office, the Lieutenant Governor assumes the position of governor temporarily. This chain of succession is established by Arizona's constitution and ensures a smooth transition of power to maintain government stability.

The reasoning for the other potential offices not taking over is grounded in their designated roles. The Secretary of State, Attorney General, and State Treasurer have distinct responsibilities that do not include acting as governor under circumstances of vacancy. The Secretary of State's duty primarily involves managing elections and maintaining official state documents, while the Attorney General focuses on legal representation for the state. The State Treasurer manages the state’s finances and does not have a succession role. Thus, in matters of gubernatorial succession, the Lieutenant Governor is specifically designated to step up when needed.
