Louisiana elects all its state legislators in the odd year just before presidential election years. All state legislators in both houses get four-year terms. The last election for Louisiana legislature was in 2007.
Louisiana has used “top-two” in all state elections starting in 1975. In the 2007 election, out of all 144 legislative races, only two incumbents were defeated for re-election in either round of voting. They were Rick Farrar, a Democrat in the 27th House district, and Carla Dartez, a Democrat in the 51st district. Both were defeated by a Republican.
