Not going to happen – the California state government’s not going to want to give up the tax revenue from the inland regions; and the current federal government probably wouldn’t be happy at the thought of one (or even two) new Republican Senators, to say nothing of the Republican Congressmen who would probably now survive redistricting. And the minor little detail that losing a portion of California’s electoral votes would gut the Democratic party like a fisherman gutting a trout. Still, the state is too large. Which is something that I’d say about Texas, too: given my druthers, I’d break up some of the larger states until we got to sixty or so*. Which is undoubtedly yet another reason why it’s probably a good thing that I’m never given my druthers.
No, I don’t even know what ‘druthers’ are, and I’m faintly afraid to check. The word’s sufficiently archaic that it probably means something fairly distasteful.
*At least one of which would be Puerto Rico. Or they could go independent. Either’s fine.
