What about The Three Californias?
I really like the idea, but 6 may be too big too soon. The Three Californias reaches the same goals but in a more palatable form that would get the population on board more thoroughly. North California, Central California, and South California. By doing this, and including resources that include the coasts and mountain ranges in all three states, the chances of approval are greatly increased. South and Central California would benefit from investing in Water Collection, Solar Power, and Desalinization Plants. All three states would be strong enough in ther own resources, then, that the chances of disapproval would drop. The 6 States plan divides natural resources "Too Much" to get the vote. By giving all "3 States" resources from the ocean to the mountains- your chances of approval increase exponentially.
