The Lieutenant Governor of Kansas has minimal constitutional responsibilities, making the office one of the weakest second-ranking offices in the United States. But, the Kansas Constitution does specifically mention in Article 1, Section 12 that the office “shall assist the governor,” though the document is silent on how that assistance shall be rendered, leaving it up to the chief executive of the state to make that determination.
In addition, the second portion of Article 1, Section 12 grants the state legislature power to confer upon the lieutenant governor any duties that it sees fit.
