The main reason the position of lieutenant governor was created was to solve the problem of succession if the governorship is vacant. If the governor is unable to fulfill their duties or if the office becomes vacant for any reason, the lieutenant governor is next in line to assume the role of governor. This ensures that there is a clear chain of command and continuity of leadership in case the governor is unable to fulfill their responsibilities. To confirm this answer, I suggest referring to the state's constitution or relevant legislation that establishes the position of lieutenant governor and outlines their role and responsibilities. Additionally, historical documents or records detailing the discussions and motivations behind the creation of the position can also provide further insight.
