Take a look into the Iron Law of Oligarchy, a theory developed by Robert Michels in 1911. Speaking to how a representative democracy can degenerate into a form of particracy or oligarchy.
"It is organization which gives birth to the dominion of the elected over the electors, of the mandataries over the mandators, of the delegates over the delegators. Who says organization, says oligarchy."
I find it an interesting bit of info, based on some of the discussions about how the Democratic party in the US is starting to become the more obvious choice for an overwhelming majority of American people (unless the Republican party seriously changes their ways).
I'm not hinting one way or the other, but take a look at it.
