or the role of gov't expanding to the ridiculuous levels we see today
well i think that one was covered, actually...we have regular elections and an elect people who favor less if that is desired (throw the bums out etc). that people don't vote or are apathetic to the degree that they are today might be another story.
the lobbyest branch of the government is clearly a powerful force that changes how our government was designed to work (i'm trying to state this in a way that doesn't judge whether that effect is good or bad).
