> The proposition that made California the way it is is the one that meant that the primaries are non-partisan and the final race is between the two top contenders.
No, it's not.
It's not even a proposition. It's that the California Republican Party tries to campaign like it's Kansas, that keeps them hovering right at the border of the level where Democrats have a 2/3 supermajority in both houses plus control of the statewide offices.
> This means that special interests in California need only present their cause through the lens of leftism and they will automatically find sympathetic candidates in the top two,
It's actually pretty rare that the jungle primary provides same party candidates (and it's never, IIRC, done “Democrat plus leftist third party”), so, no, that wouldn't be true even if the California Democratic Party was reliably leftist, which it decidedly is not, see, e.g., Dianne Feinstein.
> Contrast this with a partisan primary system. In that system, on the final ballot, it would be difficult for special interests to formulate an argument appealing to both candidates.
It's actually not, you just craft it around the local district not left-right ideology.
> for some reason, I am downvoted but there is little engagement or actual refutation of what I'm saying. If you're going to downvote, at least say something.
Downvoting is saying that something isn't a productive addition to the conversation, engaging is saying that even if it is wrong, it is. There's really no good reason to engage when downvoting, or vice versa, they serve opposing purposes.
