EUA: República vs. Democracia

Walter E. Williams sobre o contraste entre o ideal republicano e a democracia:

We often hear the claim that our nation is a democracy. That wasn't the vision of the founders. They saw democracy as another form of tyranny. If we've become a democracy, I guarantee you that the founders would be deeply disappointed by our betrayal of their vision. The founders intended, and laid out the ground rules, for our nation to be a republic.

How about a few quotations demonstrating the disdain our founders held for democracy? James Madison, Federalist Paper No. 10: In a pure democracy, "there is nothing to check the inducement to sacrifice the weaker party or the obnoxious individual." At the 1787 Constitutional Convention, Edmund Randolph said, " ... that in tracing these evils to their origin every man had found it in the turbulence and follies of democracy." John Adams said, "Remember, democracy never lasts long. It soon wastes, exhausts, and murders itself. There was never a democracy yet that did not commit suicide." Chief Justice John Marshall observed, "Between a balanced republic and a democracy, the difference is like that between order and chaos." In a word or two, the founders knew that a democracy would lead to the same kind of tyranny the colonies suffered under King George III.

Here's my question. Do Americans share the republican values laid out by our founders, and is it simply a matter of our being unschooled about the differences between a republic and a democracy? Or is it a matter of preference and we now want the kind of tyranny feared by the founders where Congress can do anything it can muster a majority vote to do? I fear it's the latter.
