Elections

Louisiana state senators serve four-year terms, with all seats up for election every four years. Louisiana holds elections for its legislature in odd years.

Louisiana holds October primaries in which candidates of all party affiliations face off, rather than deciding party nominees through separate primaries. Should a candidate finish with a majority of the primary vote, he or she is considered elected; otherwise, a runoff between the top two finishers is held in November. Louisiana is also one of only four states that hold state elections in odd-numbered years. Former Clerk of the Louisiana House Alfred "Butch" Speer was quoted as explaining:

“ For scores of years we conducted our party primaries in the winter of the odd numbered years, with any necessary 2nd primary held in January. Because Republican voter registration was so miniscule from 1877 until 1980, the general elections were mere irritants to the Democrat primary victor. Once we scrapped the partisan primary system [1975] we set the entire system up to run in the fall of the odd numbered year, our traditional election season.[1][2] ”

Louisiana elections use the Louisiana majority-vote system. All candidates compete in the same primary, and a candidate can win the election outright by receiving more than 50% of the vote. If no candidate does, the top two vote recipients from the primary advance to the general election, regardless of their partisan affiliation.
