Final answer:
If the lieutenant governor moves up to become the governor, a successor is elected to fulfill the role of lieutenant governor. Until a successor is elected, or if the lieutenant governor is absent or temporarily unable to act, the duties of the lieutenant governor are performed by the president pro tempore of the Senate.
Step-by-step explanation:
If the office of the lieutenant governor becomes vacant, a successor is elected by the members of the Senate from their ranks. Until a successor is elected, or if the lieutenant governor is absent or temporarily unable to act, the duties of the lieutenant governor are performed by the president pro tempore of the Senate.
When the lieutenant governor moves up to become the governor, a successor is elected to fulfill the role of lieutenant governor. The successor is elected by the members of the Senate from their ranks. If the lieutenant governor is absent or temporarily unable to act, the duties of the lieutenant governor are performed by the president pro tempore of the Senate.
For example, in Texas, the lieutenant governor is elected separately from the governor and serves as the president of the Senate. If the lieutenant governor becomes unable to fulfill their duties, the president pro tempore of the Senate steps in to perform those duties until a successor is elected.
