The Marxist Prog Humanist scum in the yellow counties have destroyed the entire state with their tyranny.
Total separation of the two would allow the blue (in THIS map) counties to rebuild all the good that was California 70 years ago.
The "good" California is gone forever. The only way the "good" California comes back is if millions of illegals are sent packing. And that ain't ever gonna happen short of financial collapse, disease epidemic, or civil war.
