It means power -- power to the people in the interest of constitutional equality and liberty, not a tyranny, aristocracy, oligarchy, or bad democracy.

Aristotle said there are 6 kinds of government, 3 good ones and 3 bad ones. The bad ones are where the ruler rules in their own interest. The good ones are where the ruler rules in the public interest. How many people rule: In Tyranny - 1 person rules in their own interest Monarchy - 1 person rules in the public interest (a good tyrant is a monarch) Aristocracy - a few people rule in the public interest Oligarchy - a few people rule in their own interest Democracy - all people rule in the public interest Bad Democracy - all people rule in the interest of the majority and oppress the minority
