Darcs is in the process of discovering what James Madison did in Federalist 10.

Here's the problem with your system, Darcs. 1. You can take over really tiny countries very eaily. 
2. It is easier for demagogues to convince 10,000 people all in the same area than 150,000,000 all over the country. The bigger the country, the more cultures it has and the more varied its citizen's concerns. This makes a 51% perpetual majority for one ideology impossible. 

The solution therefore is to have a weak federal government whose only business is regulating that which crosses state lines, having uniform international trade laws, protecting your rights from violence, and national defense.
