1999 Louisiana lieutenant gubernatorial election

Elections in Louisiana—with the exception of U.S. presidential elections—follow a variation of the open primary system called the jungle primary or the nonpartisan blanket primary. Candidates of any and all parties are listed on one ballot; voters need not limit themselves to the candidates of one party. Unless one candidate takes more than 50% of the vote in the first round, a run-off election is then held between the top two candidates, who may in fact be members of the same party. Texas uses this same format for its special elections. In this election, incumbent Democratic lieutenant governor Kathleen Blanco received more than 50% of the vote in the first round, so no run-off election was held.^[1]

On election day, October 23, 1999, incumbent Democratic lieutenant governor Kathleen Blanco defeated her foremost opponent Republican candidate Kevin Joseph Duplantis by a margin of 846,980 votes, thereby retaining Democratic control over the office of lieutenant governor. Blanco was sworn in for her second term on January 4, 2000.^[2]
