Jungle Primaries essentially disenfranchise voters of the minority party. It's true in CA, it's true in LA, and it's an unfortunate practice.
I completely agree. Jungle primaries wouldn't necessarily be fair in a 50-50 state either, because a larger number of viable candidates on one side could just split their votes that much that neither advances to the general election. Even when you have party A with five candidates receiving 10% on average and in a range between 5% and 17% while party B just has two two candidates that finish at 22% and 19%, candidates of party B face each other in the runoff although party A in total got more votes in the first round.
