There is no actual primary election in Louisiana. Instead, the state uses a majority voting system. If a candidate receives the majority of votes cast for the position, he or she wins. However, if no candidate reaches this threshold, a second round of voting is held between the top two votes. Any registered voter can participate in both the first and second round of elections.
