America is not a constitutional democracy. America is a constitutional republic, the first constitutional republic.
As far as we know, the Ancient Greeks had the only democracy, ever. It consisted of some officials, like an archon, who were chosen by lot and carried out the will the of the citizens. However, each citizen had a vote on all matters.
Go to war? Citizens voted, with the archon performing a function similar to that of a moderator.
Be taxed? Citizens voted.
Amount of the tax? Citizens voted.
The length of mandatory military service? Citizens voted.
That is a democracy--a direct vote by a citizen on all matters of government.
Greek democracy was not necessarily egalitarian: Discrimination came in at the point of deciding who was a citizen and who was not.
Moreover, some speculate that such a system was possible only because most citizens had slaves, which freed them up to attend the various meetings and vote. (Though, now, with the internet, I supposed we could vote directly, if anyone were of a mind to let us. Doubt they'll let us.)
In a republic, on the other hand, citizens (however chosen) vote for representatives and that is the only thing on which citizens have a right to vote.
Definition of a republic re·pub·lic
noun \ri-ˈpə-blik\
: a country that is governed by elected representatives and by an elected leader (such as a president) rather than by a king or queen
http://www.merriam-webster.com/dictionary/republicWebster's also says that the "supreme" power resides with the citizens, but that means only that they can elect representatives.
Section 4 of Article IV of the Constitution:The United States shall guarantee to every state in this union, a republican form of government, and shall protect each of them against invasion; and on application of the legislature, or of the executive (when the legislature cannot be convened), against domestic violence.
One poor slob, who thought Rhode Island was not giving the vote to enough people, sued to get the "guaranty" mentioned in the Constitution. For the occasion, the Supreme Court invented the doctrine of a "political question." A political question is one which the Court says should be resolved at the polls, not in courts. Catch 22: You sue because people can't vote and the Court tells you to resolve the problem by voting.
Also from Webster's at the link above, we get this:
<when asked by a passerby what sort of government the constitutional convention had formulated for the new nation, Benjamin Franklin memorably replied, “A republic, if you can keep it”>
That may be memorable to Webster's, but other sources say the story may be apochryphal.
The 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.
Anyway, we are a republic, not a democracy. I have no idea why everyone insists on calling the USA (or any other modern nation) a democracy, but we are all republics (or something even less democratic than a republic).
As an aside: I recently posted that the Knights of Columbus got Grover Cleveland to choose a date in September for celebration of Labor Day, as opposed to May 1, which the rest of the world celebrates in honor of the Haymarket affair. The Knights of Columbus are also responsible for insertion of "Under God" in the pledge. Interesting, because all of this happened before our first President who was not Protestant; and his Catholic religion was such a controversial issue at the time. Yet, behind the scenes, it seems Catholics were getting what they wanted.
