These places aren't homogeneous in their political tastes.

I live in a northeast blue state, but there are rural pockets that are still heavily MAGA. And I'm sure Mississippi has liberal enclaves.

That being said, I don't know what the "solution" to this problem is.

further, California is a big state. For the concept to work you'd have to split California lengthwise, the Western 1/3 would align politically how the op is assuming but the Eastern 2/3 would not. If the counter argument is majority rule then you're pretty much back to where you started with a divided population and 2 wolves + 1 lamb voting on lunch.
