I lived there 10 years, and it was obvious the state had multiple different interests. The south wants the north's water, and doesn't pay anything for it. The south is farming; the north, technology. The far north is radical environmentalism; the rest only mildly so.
I always used to suggest they split it in two - at Monterey right down the middle, since both halves would want Monterey. There's a fault line splitting it already, so its a natural division as well!
