What exactly is democracy? Abraham Lincoln said, "Of the people, by the people, and for the people." The term democracy is derived from the Greek terms "demos" (people) and "kratos" (power); hence, democracy may be thought of as "power of the people": a form of government that is based on the desire of the people.
