The framers gave us what they called a republic, but by a republic they meant a representative democracy, and by a representative democracy, they meant a government, as Madison put it in Federalist 52, that would have a branch that would be dependent upon the people alone.
Os mentores nos deram o que eles chamaram de uma república, mas por república eles queriam dizer uma democracia representativa e, por democracia representativa, eles queriam dizer um governo que, nas palavras de Madison no texto do "Federalista 52", que teria um poder que dependeria somente do povo.
