I don't think I wrote that all democrats didn't want to fix this, it was simply an illustration that there are plenty of democrats that don't want to fix it or don't care enough to do so. You have to consider that CA could have passed this long ago, it's not like this was their first chance. The fact that it took them so long in the first place to even consider it doesn't speak great things about them. There's also the recall election, they could have run someone better if this was what they were really prioritizing but that clearly isn't the case. There's also plenty of charter cities that could adopt better methods that are likely democrat strongholds and they've also sat around for the most part (although there's obviously exceptions like the SF area, where interestingly enough Newsom also tried to stop it but failed).

edit: although really I hope all you took away isn't just that I don't like democrats. I don't like anyone against fixing the voting methods be they democrat, republican, green, libertarian, independent, or any other category I failed to mention. I just pointed out democrats because supposedly they are the majority in CA and like to claim that they support a healthy democracy. In the same way, I'm happy to work with (just about) anyone who wants to fix the voting system and hope they will make their voice heard. I think it is perhaps the most important thing we need to fix right now, and is one of the main criteria I personally look at when voting for officials.
