Title: Louisiana State Senate
Content:  The president of the Louisiana State Senate is the presiding officer of the Louisiana State Senate and the highest-ranking state senator. The President is elected by the members of the state senate. Although not mandated by law or the Louisiana Constitution, the governor usually chooses the president, who in turn is usually elected by a near-unanimous, if not unanimous, vote. The president is usually chosen from the majority party, even if it is not the governor's party, although this is not always the case. One example of this is when Republican Governor Mike Foster chose Republican State Senator John J. Hainkel Jr. to serve as senate president even though the Democrats had a large majority. One factor that allows for this is that the Governor usually has support on both sides of the aisle when he first enters office so his appointees, including the senate president, are usually confirmed easily. The president is fifth in the line of succession to the governorship after the lieutenant governor, secretary of state, attorney general, and state treasurer.
