Which is NOT an executive power that governors possess? Engage in referendum Power to Appoint, Remove, and Supervise Control the state militia

Engaging in referendums is not an executive power typically held by governors. While governors have numerous responsibilities, such as appointing officials and overseeing the state militia, referendums usually require a legislative initiative or public petition to be put on the ballot, rather than direct executive action. In many states, governors do have considerable influence in shaping referendum proposals, but they can't unilaterally decide to engage in one. This helps ensure that significant changes in state policy reflect the will of the people and not just the preferences of a single political leader.
