Just to understand, if California wanted to succeed and become part of mexifornia, you would let it? All joking about California aside, such a decision would be suicidal for the government that allowed it and for the nation as a whole.
This is not even remotely comparable. And the word is secede, not succeed.
California will never succeed.
Alas...I lived there for several years so I know it and remember what a great place it was many, many years ago. Heck, maybe a war would help it. Just joking!
