Louisiana has adopted an election mechanism and timetable that is unique and not widely used in the United States. We have what is sometimes called a “jungle primary” process.
This means that for a single office, every candidate is listed on one ballot, regardless of political party affiliation. This serves as a sort of “first round.” This can be confusing for some voters, since Louisiana’s jungle primary actually occurs when the rest of the U.S. holds its general election. In order for this round to resolve the election, a single candidate must receive at least 50% of the vote. If this occurs, then that candidate wins the election outright in the first round.
