California's rules for independent party voters is another form of suppression

In Australia, only registered financial members of a party can vote in preselection (the primary). Becoming a voting member requires membership of exclusively one party, and is subject to party ratification, which can take months. Which seems potentiallly less democratic.
In California, the ability to register a party preference for free on primary day seems like a vast improvement. But then you have Republicans voting as spoilers in the Democratic primary because the Republicans aren't holding one this year.
Another issue in the US is that most states award no delegates for candidates who receive less than 15%. That seems like a perfect case for ranked-choice voting. Australia has had it for 100 years. A first step in that direction passed in the California state legislature (SB-212) but Gavin Newsom vetoed it.
As someone who cast my primary vote for somebody who has since withdrawn, I feel like America could and should do better.
(Now, that was last year. I've since left CA, as it was too expensive.)
(This release[1] does seem to corroborate what the article says, though.)

Having a completely open primary is absurd and allows people to game the primary system.
