There is no way the Democrat Party would ever go along with this. They would lose a sure 55 votes in the electoral college, jeopardize a majority of the Senators and members of Congress. These maps would cut off (Billions?) for the funding of coastal welfare, WIC and other government programs from a huge tax base to fund them. Orange County south to San Diego are Republican and they would control their State responsibility for border issues and without the pressure from Sacramento, likely end Sanctuary Cities in their area for increased Federal funding and protection.

I suspect the addition of two more States would also create a need for another Federal Court of Appeals and the possibility of taking away authority from the 9th Circuit now housed in San Francisco. That alone would be enough for Democrats to shoot this down in the Congress and Senate. 

Having said that, I'm glad I already don't live in the Sacramento or Los Angeles areas.
