The Founding Fathers did not give us a Democracy. They gave us a Federal Republic, with the power to protect the separate Republics (guarantee clause in the Constitution) in the several States. If you read the Federalist Paper #10, you will see that preventing a Democracy was one of Madison's purposes in drafting our Constitution. You will also see why.
Democracy works in Switzerland, and in New Hampshire town meetings; but in most places it rapidly degenerates into mob rule. It is not the ultimate achievement of the human experience! The efforts of the Left to convert our Republic into a Democracy, are behind most of the things we do not like in 20th Century America.
