Sigh. This country is screwed. Seriously.
Our own President doesn't even understand the form of government he was elected to and given the responsibility of preserving.
What a moron.
Let's clear this up again. For like the umteenth time.
A Democracy
The chief characteristic and distinguishing feature of a Democracy is: Rule by Omnipotent Majority. In a Democracy, The Individual, and any group of Individuals composing any Minority, have no protection against the unlimited power of The Majority. It is a case of Majority-over-Man.
This is true whether it be a Direct Democracy, or a Representative Democracy. In the direct type, applicable only to a small number of people as in the little city-states of ancient Greece, or in a New England town-meeting, all of the electorate assemble to debate and decide all government questions, and all decisions are reached by a majority vote (of at least half-plus-one). Decisions of The Majority in a New England town-meeting are, of course, subject to the Constitutions of the State and of the United States which protect The Individual’s rights; so, in this case, The Majority is not omnipotent and such a town-meeting is, therefore, not an example of a true Direct Democracy. Under a Representative Democracy like Britain’s parliamentary form of government, the people elect representatives to the national legislature--the elective body there being the House of Commons--and it functions by a similar vote of at least half-plus-one in making all legislative decisions.
In both the Direct type and the Representative type of Democracy, The Majority’s power is absolute and unlimited; its decisions are unappealable under the legal system established to give effect to this form of government. This opens the door to unlimited Tyranny-by-Majority. This was what The Framers of the United States Constitution meant in 1787, in debates in the Federal (framing) Convention, when they condemned the "excesses of democracy" and abuses under any Democracy of the unalienable rights of The Individual by The Majority.
A Republic
A Republic, on the other hand, has a very different purpose and an entirely different form, or system, of government. Its purpose is to control The Majority strictly, as well as all others among the people, primarily to protect The Individual’s God-given, unalienable rights and therefore for the protection of the rights of The Minority, of all minorities, and the liberties of people in general.
The definition of a Republic is: a constitutionally limited government of the representative type, created by a written Constitution--adopted by the people and changeable (from its original meaning) by them only by its amendment--with its powers divided between three separate Branches: Executive, Legislative and Judicial. Here the term "the people" means, of course, the electorate.
An Important Distinction: Democracy versus Republic
I'm reminded of a great quote after reading that underinformed tweet from the President. It was by Henry Menken. He was a newspaper guy back in the early 1900s.
What Henry said, and correctly so, if we're to take our President's own words at face value, was that ''as democracy is perfected, the office represents, more and more closely, the inner soul of the people. We move toward a lofty ideal. On some great and glorious day the plain folks of the land will reach their heart's desire at last, and the White House will be adorned by a downright moron.''
