The trouble with dividing the USA is that there really isn't a nice clean line to make the division. California is actually three distinct regions (each of which could make their own state): the North Coast, the South Coast, and the Interior. The interior would probably prefer to join Mississipi. Then there are parts of Mississippi that would like to join the Two Coasts.
