The 2014 United States Senate election in Louisiana was held on November 4, 2014, to elect a member of the United States Senate to represent the State of Louisiana. As no candidate won a majority of the vote, a runoff was held on December 6, 2014. Incumbent Democratic Senator Mary Landrieu ran for re-election to a fourth term in office against Republican U.S. Representative Bill Cassidy and several other candidates. Under Louisiana's jungle primary system, all candidates appear on the same ballot, regardless of party and voters may vote for any candidate, regardless of their party affiliation. Louisiana is the only state that has a jungle primary system (California and Washington have a similar "top two primary" system). Since no candidate received a majority of the vote in the primary election, a runoff election was held on December 6 between the top two candidates, Landrieu and Cassidy. In the December 6 runoff, Cassidy defeated Landrieu by 56% to 44%, settling the fate of the final Senate seat of the 2014 midterm elections and becoming the first Republican to hold this seat in 132 years. Cassidy's victory gave the Republicans 54 seats in the 114th Congress, and marked the first time since the resignation of William Pitt Kellogg in 1872 that both of Louisiana's Senate seats were held by Republicans.
