From our Constitution, Article 4, Section 4:
The United States shall guarantee to every State in this Union a Republican Form of Government
And from our Pledge of allegiance:
"I pledge allegiance to the flag of the United States of America, and to the republic for which it stands, one nation under God, indivisible, with liberty and justice for all."
And in case you missed it, from Webster’s Dictionary 1828 - Online Edition :
DEMOCRACY, noun [Gr. People, and to possess, to govern.] ”Government by the people; a form of government, in which the supreme power is lodged in the hands of the people collectively, or in which the people exercise the powers of legislation. Such was the government of Athens.”
REPUB’LIC, noun [Latin respublica; res and publica; public affairs.]
”A commonwealth; a state in which the exercise of the sovereign power is lodged in representatives elected by the people. In modern usage, it differs from a democracy or democratic state, in which the people exercise the powers of sovereignty in person. Yet the democracies of Greece are often called republics.”
And from Federalist Paper 10
The other point of difference is, the greater number of citizens and extent of territory which may be brought within the compass of republican than of democratic government; and it is this circumstance principally which renders factious combinations less to be dreaded in the former than in the latter . . . Hence, it clearly appears, that the same advantage which a republic has over a democracy, in controlling the effects of faction, is enjoyed by a large over a small republic,–is enjoyed by the Union over the States composing it.
Under our “Republican Form of Government” we don’t vote on legislation as is done in a democracy. Under our “Republican Form of Government” which is guaranteed by Article 4, Section 4, elected representatives are entrusted with “all legislative powers”, limited by a written constitution as distinguished from a democracy in which the people exercise legislative power using their vote, and why democracy is often referred to mob rule government.
Now, once again I ask, why do you have trouble referring to our system as a constitutionally limited “Republican Form of Government”, or, a constitutionally limited representative republic, both of which accurately describe our system of government?
At the close of the Constitutional Convention in Philadelphia on September 18, 1787, a Mrs. Powel anxiously awaited the results and as Benjamin Franklin emerged from the long task now finished asked him directly,
Well, Doctor, what have we got? A republic or a monarchy?'A republic, if you can keep it,’ responded Franklin.
