Should a county be allowed to secede from its respective state?
Absolutely. Positively. No question. Especially a state like California that is *so* large - and so out of control in so many ways. I'd be seriously tempted to move to the state of Jefferson if they are ever able to get that done! Could save CA.
Unless the state legislature votes to approve it.
Yeah exactly as long as it's done constitutionally it's fine
There is a specific process to secede from a state, which includes approval by current state gov & Congress.
If it goes through the legal process described in the Constitution then sure.
