The political balance in Louisiana was heavily affected by the post-Hurricane Katrina departure from New Orleans. Heavily Democratic New Orleans lost some 1/3 of its population. The overall effect reduced the Democrats' base of support in the state and turned Louisiana into a Republican-leaning state thereafter. New Orleans remained Democratic, electing Mitch Landrieu as mayor in February 2010. In the 2008 elections, Louisiana sent a mixed result, with the election of U.S. Senator John McCain for President and the reelection of Democratic U.S. Senator Mary Landrieu. The other senator, at the time, was Republican David Vitter.
Since that election, Republicans have rapidly come to control nearly every federal and statewide office. Both U.S. Senators, Bill Cassidy and John Kennedy, are Republicans. Republicans also hold four of the six U.S. Representative seats from Louisiana. Every statewide office is held by a Republican, and both chambers of the state legislature are majority Republican. By contrast, in 1960, not a single Republican served in either house of the Louisiana legislature. The first Republicans to serve in the legislature since Reconstruction were not elected until 1964, and both—Morley A. Hudson and Taylor W. O'Hearn—came from Shreveport.
In 2010, several Democrats switched parties bringing the statehouse under Republican control. In 2011, the special election victories of Fred Mills and Jonathan Perry switched the balance of power in the state senate, leaving Republicans in control of the state legislature for the first time since Reconstruction. Also, the party switch of Attorney General Buddy Caldwell caused the Republican party to control every statewide office. However, this was broken in 2015, when Democrat John Bel Edwards won the governor's race.
Republicans won the first Senate seat since Reconstruction in 2004, with the election of David Vitter. He became the first popularly elected Republican Senator as well. In 2014, Republicans won both Senate seats for the first time since 1872.
