Is Democracy Best?

Although they are all considered social contract theorists, Hobbes, Locke, and Rousseau had very different ideas of what form that social contract should take, and not all supported democracy as the best style of government.

In a House of Commons Speech (November 11, 1947), Winston Churchill said, "Democracy is the worst form of government, except for all those other forms that have been tried from time to time."

Given Churchill's comment, and the works of the social contract theorists, is Democracy the best form of government today?
