So how can Louisiana have its current system for electing senators? Isn't Landrieux going to have to run with the runner-up in December if neither gets a majority on Election Day?
Louisiana uses the Napolionic Law for its basic laws - parishers instead of counties. I don't know what thiis entails, but I don't think they have primaries. Everyone runs. The one with 50% of the vote wins, or there is a run-off between the top 2.
Napolionic Law wasn't the basis for switching to the open primary in LA, if I remember correctly. It was done to appease the Republicans and at the same time they thought that no Republican would ever come in second in an open primary so there would be always a Democrat winning.... But that's changed significantly and Republicans do win even statewide.
The runoff if needed will be on Dec. 7, should none of the candidates secure a majority.... The original lawsuit was arguing the election of a candidate in Oct. thus prior to the Federal date. Not sure what the ruling would be for a runoff after the Federal date.... interesting
