The experiment in American Exceptionalism was a near total failure. The Articles of Confederation were unworkable. Some of the finest minds in the nation had met and, by committee, crafted a "Constitution." How to persuade the American people that this "Consitution" should be embraced?
Thus began the first and most successful marketing campaign of the new America. The Federalist Papers, today considered something akin to a legistlative history on the Constitution, were in the 18th Century a sales effort -- to inform and to persuade. The Federalist Papers took full advantage of the vast media opportunities of the day. Newpapers.
Alexander Hamilton, a foreign born bastard (literally, in the terms of the day) was the lead author of the Fderalist Papers. In writing of the Judiciary, Hamilton referred to it as the "least dangerous branch" of the planned federal government.
How, then, did the few men who composed the "least dangerous branch" cause a retired but not sedentary Thomas Jefferson to fear the young nation was committing a felo de se -- an act of suicide?
