I don't live in in CA, so my view from the outside might not be completely accurate, but what I have noted over the last 40+ years is that no matter WHAT the PEOPLE of CA vote in, the only things that go into effect are those in line with the liberal/leftist agenda.
Public propositions that don't, like the ones to lower the people's cost for gasoline, auto insurance, car tabs, and everything else that isn't in line with what the powers that be want, doesn't go into effect.
It goes into court. And after YEARS in court (sometimes decades??) after public support has faded, it is ruled against. Net effect, zero change in people's lives. What ever it was that they voted against stays in place, and then more and more is added to it, over time, and not always a long time, either.
Things that agree with the leftist agenda are ramrodded through, implemented as fast as possible, and when taken to court, rapidly ruled in favor of. That MAY not be how it actually is, but that is what it looks like from outside, to me.
