Well, try to imagine what it would be like if each and every state could leave the Union over any issue that some politician got the populace jacked up about?
First would be the Confederacy, but then other states would withdraw from the “Union”, and the Confederacy also.
Then, North America would have many smaller states with different ethnic concentrations being agitated by politicians; similar to the Balkans.
How’s that working out for them? I believe the outcome is knowable to most people.
