The Missouri Senate is the upper chamber of the Missouri General Assembly. It has 34 members, representing districts with an average population of 181,000.[1] Its members serve four-year terms, with half the seats being up for election every two years. The Senate chooses a President Pro Tempore to serve in the absence of the lieutenant governor or when he shall have to exercise the office of governor of Missouri if there is a vacancy in that office due to death, resignation, impeachment, or incapacitation.[2]
Members of the Missouri General Assembly are prohibited from serving more than eight years in either the state house of representatives or state senate, or a total of sixteen years, due to statutory term limits.[3]
