Okay, so it's Northern California - although it's hardly a hotbed of conservatism - , the valleys, Orange County and San Diego county. Hmmm... I think we may have to carve up a bit of NoCal too. I say, in the Bay Area, we keep the Pennisula, the South Bay and the very East Bay. Drop off Marin County and the near East Bay. Forget about Humboldt County but Mendocino, Sonoma, Napa and the rest are fine.
In summary, it appears to me that the places without water will be Humboldt, San Fran, Marin, Oakland, and LA. Sounds good to me. Although I do still love the City by the Bay.
