There is no going back. NYC will go Conservative before the entire West Coast does, which means it will never happen.
There has been a deliberate, engineered change in demographics in California.
California was once a predominantly high skill, highly educated state with a dynamic economy . That has been changed to an increasingly low skill, poorly educated and low functioning third world type population with third world corruption and voting trends.
The third world model of a small, very wealthy elite at the top and huge underclass is increasingly the California norm as the middle class is either wiped out or forced to leave
Businesses are leaving in droves
At the state and local level, Far Left Democrat politicians representative of California's new third world demographics have taken control. They conduct their affairs in typical corrupt third world fashion and make laws that serve their own interests
Election law has been changed so that some elections are between two Democrats with no Republican even on the ballot . All Republicans have become B1 Bob Dornan in California
California will require a serious crisis before any changes take place,
