You didn't actually provide the link mentioned, but here's what I would say:
Constitutional officials of the Maine state government:
Governor (head of the Executive Branch of state government)
Secretary of State (a constitutional officer in state government)
Attorney General (a constitutional officer in state government)
Maine is one of five states that don't have an office of Lieutenant Governor.
Maine does not have an official called the "State Comptroller." There is a statutory officer called the State Auditor, which is responsible for auditing the state's finances. There is also an Office of the State Controller ... but technically no office called "comptroller."
