I think the day is approaching.
If the republicans take the white house in 2012 and control the senate and house then the best way to avoid absolute disaster is to let the country split apart.
Red states becoming a new free nation and blue states becoming a hopeless welfare disaster.
If the split is attempted when democrats control the government then millions will die in the conflagration.
I believe the same thing... sometime in the next 20 years. The nation is way too ideologically split to survive as a 50-state entity. A breakup is going to have to happen.
