I like this mental exercise, DUmmy. In typical DUmmy fashion, you have failed to consider the consequences.
Here is the 2008 electoral map of the lower 48:
DUmmyland is made up of four unconnected territories- East Libertopia, West Libertopia,
Mexitopia del Norte, and
Cubatopia del Norte. Lots of hungry mouths and hands out for "free" government cheese. Not so much farmland, oil, or coal. Look forward to cold, hungry winters.
The red state territory shall continue to be known as "The United States of America". Why? Because every red state shares at least one border with another red state. I see oil and coal in the red states; cattle, wheat, and corn. With the natural defection of the military from DUmmyland to the USA, they would bring aircraft, ships, tanks, and rail stock with them. The Gulf Coast is a natural and easily defensible free trade conduit with the rest of the world.
Remember all of those warships and planes, DUmmies? How will you defend your territory, with uptwinkles and healing white light? Guess who will control the Mississippi River and the sea lanes? Guess who will be paying tariffs to ship goods in and out?
In six months, who will be our bitches? Suffice it to say, it will be you.
Bring it, DUmmies. Just bring it.
