California once was run by alternating conservatives and mostly centrist Democrats.
True, paleo-liberal governors like Pat Brown greatly expanded the welfare state. But they also believed in pushing integration, building freeways, dams, aqueducts, and power plants, while preventing forest fires, directing the mentally ill into state hospitals, and ensuring the state enhanced the housing, timber, oil and gas, nuclear, and agricultural industries.
So why and how would anyone deliberately destroy that heritage?
Why allow California to have the highest aggregate basket of income, sales, property, and capital gains taxes in the nation, the highest gas and power prices in the continental United States, and nearly the worst schools and infrastructure, the largest populations of homeless, welfare recipients, illegal aliens, and, soon, criminals?
Remember that the left-wing of the Democratic Party became hyper-wealthy through globalization and the tech revolution. Coastal universities like Caltech, Stanford, UC Berkeley USC, and UCLA became global nexuses of millions who flocked to California to learn business, engineering, science, math, and the professions.
University endowments were no longer measured in the hundreds of millions of dollars but in the many billions. Hollywood and professional sports now had a lucrative worldwide audience of billions.
The market capitalization of Silicon Valley was to be measured in the trillions of dollars, as the world bought iPhones, iPads, and MacBooks to Google, tweet, and use Facebook. The result was the greatest concentration of wealth in such a small space in the history of civilization.
