@152...
Ok then...
In republics such as the United States the executive is legitimated both by a constitution and by popular suffrage. In the United States, James Madison defined republic in terms of representative democracy as opposed to direct democracy.
"A republic, by which I mean a government in which the scheme of representation takes place, opens a different prospect, and promises the cure for which we are seeking. Let us examine the points in which it varies from pure democracy ...", from James Madison. The Federalist, Number 10, The New York Packet, 23 Nov., 1787
you may wish to read the Federalist Papers.
in which part are you incorrect? where you believe, among other things you have cited, that: "If he does not vote as his constituency desires, he is not representing them as he is dictated by the Constitution."
the bold part is wrong, it is opinion, not law of this land. nor will ever be -- not and retain peace and justice for all.
if you are NOT saying that the U.S. Constitution created a direct democracy, then please clarify yourself. however, the dictionary definition of "republic" does NOT contradict the meaning in U.S. government, that is, "republic" does NOT mean direct or pure democracy. again, that is no contradiction to old Merriam.
and again Mr. Madison (Federalist Papers):
In the United States, James Madison defined republic in terms of representative democracy as opposed to direct democracy, and this usage is still employed by many viewing themselves as "republicans".
In modern political science, republicanism refers to a specific ideology that is based on civic virtue. Civic virtue... commies. ;-)
