It just seems wrong to me, kind of like not allowing divorces. If states don’t see eye to eye on most issues anymore, why should they be forced to stay together? Forcing 2 or more parties with wildly different outlooks on things to stay together just creates division and conflict. Everyone should be allowed to go their own way, for their good and others’. Saying this as someone from Massachusetts - I’d really support my state seceding and forming some sort of federation with other like-minded Northeastern states.
At least as I understand it (and there’s a good chance I’m wrong) there’s nothing in US law preventing a state from seceding. It was determined that the way the southern states decided to do it in the runup to the civil war was unconstitutional (and possibly treasonous? seditious? Something like that), but there’s no law saying a state can’t secede. It’s just that there’s no defined process for it and the only way it has been tried was determined to be wrong.
From what I’ve read on the topic, there is technically a way it could be done. The country would basically have to follow the same process as passing a constitutional amendment, just with an additional step.
So, not technically impossible just so difficult that it is effectively impossible.
