Which of the following roles is not an elected position in Missouri government?

The Chief of Staff is a role that is typically appointed rather than elected. In Missouri, the Chief of Staff serves directly under the Governor or other elected officials and is responsible for managing the operations of the office and coordinating activities. This position does not go through a public election process, but rather is filled by the executive based on their discretion.

In contrast, the State Auditor, Secretary of State, and Attorney General are all positions that are filled through elections. These officials are chosen by the voters in Missouri to serve in roles that involve significant responsibilities in government oversight, administration of state elections, and legal representation of the state, respectively. Each of these roles is established by the Missouri Constitution and requires candidates to campaign for public support to assume office.
