Reality check... folks generally get the government... they deserve.
Actually Californias current situation is largely a result of federal policies.
California passed prop 187, the federal government didnt overturn part of it, or make adjustments, they nullified what the state residents passed to stop the state from being taken over shortly before the demographics had shifted so far that they would never be able to do it again.
All while the federal government failed to properly enforce immigration restrictions, or secure the border, which at the time primarily impacted California.
So California tried to remove the incentives to illegal immigration since they could not physically stop it as that was the jurisdiction of the federal government, and was shot down by the federal government, even when passed by almost every county in the state except some parts of the San Francisco Bay Area.
Ronald Reagan as federal President of the United States had previously granted amnesty and turned illegals mostly residing in California into legal citizens and voters in the state. Giving the vote to millions of new people that would primarly vote along racial lines to never enforce immigration that almost kept them from going where they wanted. Yet even after those millions of new voters it would be some time after prop 187 years later that the demographics had given the invasion and their children the vote.
Once again something from the federal level forced California to change rapidly into an entirely different population.
So the Federal government actually forced California to be taken over against the will and wishes of the prior citizens. Once those immigrants and their children, and they have a lot of children as the fastest growing demographic in the nation, became the primary citizen of the state, the entire thing shifted and now the state trips over itself to be a sanctuary state.
Additionaly currently we have more foreign born in the United States than any time in almost a century, but they are not evenly distrubted and California has the largest share:

This includes a lot of legal immigrants, once again with California having a disproportional amount of them employed by the various tech companies and others importing the least expensive source of skilled labor. A lot of Indians and Chinese. It is quite a visible change in just a decade, with muslim head dresses and similar things in public rare just a decade ago now common place as well. This is not to say any of these groups are bad, but that the demographics and population had shifted to something quite different in a very short span as a result of the federal government, eventually it had shifted so much that the new state population outnumbered the prior state population enough to outvote them.
So California has the government the Federal Government forced it to have. More than half of the state is foreign born or the children of foreign born, and it all happened in just a few decades, and against the will of most of the previous citizens.
They now outnumber the previous citizens, and so the State was essentially forced to accept invasion by the Federal Government and be outvoted by the invaders.
Left leaning politicians take this new and overwhelming vote and run with it, doing all they had previously wanted to do.
