While I didn’t used to think this way, I sure have no problem splitting us into two or three Nations. What we have now is unworkably absurd.
How about 50 distinct states, each with its own government, loosely bound by a limited federal government?
The Balkanization of the territory once known as “the United States of America” is well begun. Like iron filings rearranging themselves in a magnetic field, there are clusterings around the lines of greater attraction, and a thinning out in those areas in between where the attractive force is less.
Once set up, these lines are much harder to break.
