THE U.S. OF THE FOUNDERS IS A REPUBLIC, WITH A REPUBLICAN FORM OF GOVERNMENT, ARTICLE 4 SECTION 4 OF THE CONSTITUTION.
IT IS A MIXED GOVERNMENT, COMPOSED OF A MONARCHY, ARISTOCRACY AND A DEMOCRACY , WITH EACH BALANCED AGAINST THE OTHER.
POWER IS DIVIDED, BETWEEN THE STATES AND THE PEOPLE....TO PREVENT ALL POWER CONCENTRATED INTO ONE ENTITY WHICH WOULD CAUSE TYRANNY.
DEMOCRATIC FORM OF GOVERNMENT LIKE THOSE USING DEMOCRACY IS WERE POWER IS CONCENTRATED ONLY INTO THE HANDS OF THE PEOPLE, AND THEY RULE WITH ABSOLUTE POWER.
A republic and a democracy are identical in every aspect except one. In a republic the sovereignty is in each individual person. In a democracy the sovereignty is in the group.
Republic. That form of government in which the powers of sovereignty are vested in the people and are exercised by the people, either directly, or through representatives chosen by the people, to whome those powers are specially delegated. [NOTE: The word "people" may be either plural or singular. In a republic the group only has advisory powers; the sovereign individual is free to reject the majority group-think. USA/exception: if 100% of a jury convicts, then the individual loses sovereignty and is subject to group-think as in a democracy.]
Democracy. That form of government in which the sovereign power resides in and is exercised by the whole body of free citizens directly or indirectly through a system of representation, as distinguished from a monarchy, aristocracy, or oligarchy. [NOTE: In a pure democracy, 51% beats 49%. In other words, the minority has no rights. The minority only has those privileges granted by the dictatorship of the majority.]
