"Democracy is two wolves and a lamb voting on what to have for lunch. Liberty is a well-armed lamb contesting the vote." Benjamin Franklin, 1759
Democracy: Two wolves and a sheep voting on what to have for dinner.
Representative democracy: Two thousand wolves and one thousand sheep electing two wolves and a sheep who vote on what to have for dinner.
Constitutional Republic: Two thousand wolves and one thousand sheep electing two wolves and a sheep who vote on what to have for dinner, but are restricted by a Constitution that says they cannot eat sheep. The Supreme Court then votes 5 wolves to 4 sheep that mutton does not count as sheep.
Liberty: Well-armed sheep contesting the above votes.
