Mary Landrieu Loses Senate Reelection Bid in Louisiana to Republican Challenger Bill Cassidy
Republican Rep. Bill Cassidy defeated Democratic incumbent Sen. Mary Landrieu in Saturday's Louisiana Senate run-off race.
Under Louisiana's primary system, all candidates appear on the same ballot, despite political party. None of the candidates received 50% of the vote in the November 4th election, forcing this run-off election.
With Bill Cassidy's victory, Republicans will hold 54 seats when the Senate convenes in January for the 114th Congress, nine more than they have currently.
