Speaking theoretically:
I’d bet that there are nuclear weapons on CA soil, possibly controlled by people whose loyalties would be divided. Not to mention the ability to purchase such if it really came down to it.
The genie has been out of the bottle for almost 67 years now.
But anyway, I could eventually see an un-contested breakup of the USA. It happened in the Soviet Union in the 90s, even though previous attempts had been violently repressed.
