In his notes from the Constitutional Convention of 1787, one of Maryland's delegates, Dr. James McHenry -- which were first published in The American Historical Review, vol. 11, 1906, he wrote in an anecdote on p. 618: “A lady asked Dr. Franklin Well Doctor what have we got a republic or a monarchy. A republic replied the Doctor if you can keep it.”
Well, we haven't kept it. Let's stop kidding ourselves. That battle has been lost. All the furniture is still arranged as it was, and there is still plenty of lip-service to our institutions; but the imperious occupants of our houses of government are running things now as though we had a socialist state.
Don't be deceived by references to "democracy." Without a Republic, a democracy can be as totalitarian as Stalinist Soviet empire. Read J. L. Talmon's The Origins of Totalitarian Democracy, a study of J.J. Rousseau's Social Contract, or Groen van Prinsterer's Unbelief and Revolution, a study of how Rousseau's democratic ideology played out in the French Revolution.
