2015 Louisiana lieutenant gubernatorial election
The 2015 Louisiana lieutenant gubernatorial election took place on October 24, 2015, to elect the Lieutenant Governor of Louisiana, with a runoff election held on November 21, 2015. Incumbent Republican Lieutenant Governor Jay Dardenne did not run for re-election to a second full term in office. He instead ran for Governor. Billy Nungesser won the election defeating Kip Holden, despite a Democratic victory in the gubernatorial election, in which John Bel Edwards defeated David Vitter by a similar margin. Under Louisiana's jungle primary system, all candidates appeared on the same ballot, regardless of  party and voters may vote for any candidate, regardless of their party affiliation. Since no candidate received a majority of the vote during the primary election, a runoff election was held on November 21, 2015 between Holden and Nungesser. Louisiana is the only state that has a jungle primary system (California and Washington have a similar "top two primary" system).
