Absolutely ludicrous. It’s a waste of time to even discus. The federal government will never let it happen essentially ceding 1/7 of our economy,essential military bases and West coast to Mexico and China etc. A more realistic scenario is splitting California up into new states one of which “Jefferson” will be “red” right off the bat. Northern, Central,and Western California are not as insane as Southern California.
Later, California voted very narrowly for Wilson in the 1916 election--otherwise he would have lost. Would President Hughes have gone to war with Germany in 1917?
Two "Democrat Wars" (as Bob Dole would call them) because of California.
It is not up to them. The decision to secede lies with the people of CA and no one else. I wish them success in their attempt.
