Yes, and that statistic is why every democracy in history devolves into despotisim. It is also why America was designed to be a Republic.
But that can only stand on the morals of its people, sadly that has failed the test of time.
Yes, but the essence of a republic is that it must be managed by some sort of leadership cadre, a/k/a an "establishment" -- whether or not the latter term is recognized explicitly.
Therefore, perhaps we have a fundamental contradiction between (a) the denizens of Trumpland, who seemingly wish to destroy any vestiges of a governmental leadership cadre, and (b) the republican ideals of our Founding Fathers.
In any case, the 2016 election cycle may well mark the beginning of the end for the Republic envisioned by our founders:
Hilary will destroy what's left of our Constitutional tradition by her SCOTUS picks, whereas Mr. Trump appears intent on destroying it by his demagogic, no-nothing appeals to a WWE-loving public that yearns for a Latin-style Caudillo, a Bonaparte, a proverbial Man on a White Horse.
