Right, because in failing (and sometimes before failing), it leads to unbridled tyranny. Which is, I point out, not democracy. Having a constitutionally limited government is a good plan. But constitutionality is orthogonal to whether or not you have a democracy.
- it was an utter failure in ancient Greece; that is precisely why the U.S. is not a democracy. A constitutional republic has the best track record - that would be America.
Sigh. Does or does not our Constitution establish a democratic union, and lay down the rules for it's operation in rather specific detail, Mr. Logical?
What you speak of is UTOPIA. it is not possible to have a perfect democracy because power corrupts and absolute power corrupts aboslutely. That is precisely why we have checks and balances - "the heart of man is desperately wicked - who can know it" (Jer. 17:9) The liberals also dream of utopia - a John Lennon imagine-land where all is peace and love and dope (dream on liberals!).
