A state's lieutenant governor serves as second-in-command in the executive branch.
Explanation:
The lieutenant-governor position is the state equivalent of the vice president in the federal government: it is the person who assists the governor, being the second-in-command in the state's executive power and who replaces the governor in case he cannot exercise its function. In America, 45 states have this position (only Maine, New Hampshire, Wyoming, Oregon and Arizona do not have it). Generally, the functions of this position are very diverse: in some cases, it directs questions of internal policy, relations with the federal government and specific projects, while in others it performs much more limited functions.
