Dividing up America

Timdido's link, and a couple others brought an idea to my mind. Maybe we could let some of the blue sections of America split off to form their own sort of nation-sections. We would just collect some slight tax from them to pay for a small amount of oversight to ensure things like commerce continuing across the new border. We would also expect them to follow some limited guidelines since they would still be part of a kind of partnership with the rest of us. In large part though, we would leave each other alone to live as each of us sees fit. Of course, this idea only works well if the top-level government is nice and unobtrusive so that it doesn't mess up the lives of the people who want to live according to the values of their choosen section. What a grand liberal idea this could be...
