From 1978 until 2006 Louisiana used the Jungle Primary, also known as the Nonpartisan Blanket Primary or Top Two Primary, for Congressional elections. This system is still used for state and local elections in Louisiana, but was discontinued in 2008.
On April 7th, the the Louisiana House and Governmental Affairs Committee unanimously passed HB 292. Congressional elections would be converted back to the Jungle Primary with the first round occurring in November. If no one received a majority in November, a runoff would be held in December. HB 292 was written and is being spear-headed by Rep. Hunter Greene, a Republican of Baton Rouge.
While the bill is likely harmful to third parties, it represents a major improvement over the old Jungle Primary, which did not allow third parties at all–only Republicans, Democrats, and “No Party”. Richard Winger, of Ballot Access News, said of the bill:
Top-two isn’t nearly so bad when the first round is in November. No candidate is cut out of the summer and fall campaign season.
