A fellow by the name of Andrew Tanner has been writing articles outlining the split of the USA.

One good point that he makes is that when governance at the federal level is more or less absolved, the various state legislatures will no longer have the circus in Washington in their background. These legislatures can focus on what is best for their states.

Check Andrew Tanner out--if you have not encountered his work.

But I still think we need to go beyond whatever Andrew is conjuring.
