I said earlier that Calexit would give Northern Cal an opening to split Cal in two.
It should be split into three states and give what is left over to Mexico. Sothern CA goes to Mexico and good riddance.
Central CA is one state, Northern CA is another and the East West corridor from Amador County to the bay area is another and would include the area of San Jose to the north bay and Sacramento. Now that would be paradise. My main concern is that the area of Yosemite would be included in any restructuring with San Francisco and Sacramento.
