Coastal California - The coastal counties from Mendocino to SLO and inland to pick up Yolo and Sacto.
Jefferson - Humbolt, Del Norte and all the counties north of Yolo and possibly parts of Oregon south of Lane County.
East California - Inland counties from Nevada County south to Kern.
Los Angeles (or something) - Santa Barbara, Ventura, LA and the southwest corner of San Berardino bordering LA County.
South California - Orange, San Diego, Riverside, Imperial and that portion of San Bernardino that doesn't commute to LA.
That would give us three conservative states and two leftist states and would shift the political balance further west in accordance with population patterns.
That would be only temporary as libs would soon move out of the hellhole states created by them and into the comparatively decent red states. They would then proceed to turn them into blue states and more Dem U.S. Senators.
