Louisiana works by having a free-for-all election, followed by a run off of the top two candidates if no one gets over 50%, right?
This sounds like brilliant Rovian strategy: get a Democrat to run as a Republican against Landrieu, and once he’s already committed, stick a true conservative in the race. If all works well, Kennedy will split Landrieu’s vote and knock her out, leaving the runoff between the two Republicans. Sounds like a sure win strategy to me.
It doesn’t work that way any more. The “jungle primary” ended this year. There will be a party primary followed by a general election.
