It would also wipe out a substantial piece of California's water supply. I'm not sure that the left would want that, given what a commodity water apparently is in California already.
That said, splitting California into 2 or 3 states would not necessarily be a bad idea. Outside of San-Fran, LA, and the southern counties, the state is probably fairly moderate/conservative. Certainly, most of the people actually working on the Oroville situation right now are probably not snowflakes.
IMHO, of course.
Seems like when you go inland or south from S.F, things get less Leftist.
