For states with jungle-type primaries (Louisiana, California, Washington), what do state laws allow/direct when one of the two finalists withdraws/dies between the primary and general/run-off election? I'm sure that each state has a different outcome for this situation, but I doubt that the party of the withdrawn candidate gets to name a replacement. Perhaps the third place finisher in the primary moves up to the general/runoff? It doesn't seem right that the other finalist would be declared the winner, especially in the case of a death. I look forward to seeing any responses.
Yes, the Jungle system is incredibly bad for myriad reasons.
Not to mention that it's an incredible drain to put on financially. It would be far better to just have IRV, if you want multiple rounds that bad.
