California voters have gathered enough signatures to put the measure to split California on the ballot ballot on November. Undoubtedly, about the only things Democrats are thinking about is they believe adding four new US Senators would swing the US Senate away from Republican control. It is a lot more complicated than that. The same idea is floated to break Texas into 5 parts.
A vote of California voters is not enough. For an existing state to be subdivided – as West Virginia was split from Virginia during the civil war, a process is required in the Constitution.
First, the California Legislature would have to approve the request and the proposed state constitutions. That might happen. But Congress must approve the change. Creating more states would dilute the power of small states like Vermont. It is not a sure thing that even a Democratic controlled Congress would approve the request. Note that this decision is left up to Congress – the President has no veto power.
The most immediate problem, if approved, would be responsibility for the existing $83 billion in general obligation debt. The entities who loaned the money did so based on the full faith and credit of the entire state.
The next huge issue is water rights and management of the California dams and irrigation systems. The water for Los Angeles comes from Northern California and the Colorado River from the East. Wars have been fought over less. This is just the beginning.
