Like I've suggested before, just split the state in half.
Starting just above San Francisco draw a line at say a 45 to 60 angle degree south east to eastern border.
Voila, Northern California and southern California.
That would let liberal nirvana flourish and destroy itself in the south while conservative north could undo and restore itself to sanity.
North will keep control of the water&ag south can have Hollywood & silicon valley.
Let natural selection prevail.
