Louisiana’s legislature will probably pass HB 292 this year. It eliminates party nominees for Congressional elections. It says that all candidates for Congress would run in November on a single ballot, and all voters would use that ballot. If anyone gets 50% in November, that person is elected. Otherwise, there would be a run-off in December.
It’s not clear that the legislature will make the change effective this year. Bayou Buzz, a Louisiana politics blog, discusses the consequences for particular members of Congress if the bill takes effect this year. The existing system in Louisiana for congressional elections is a semi-closed primary system. When the semi-closed primary system was used in 2008 for the first time, two incumbent members of Congress were defeated for re-election.
Bayou Buzz also discusses the possibility that the U.S. Justice Department, Voting Rights Section, might not approve HB 292, or might not approve as applied to this year’s election.
