Answer:
The government is not all-powerful. It has no right to try to do more than we've explicitly authorized it to do. ... The principle of limited government expands upon the idea of popular sovereignty (the idea that legitimate political power must derive from the consent of the governed). or
Popular sovereignty is a doctrine which holds that the people control the political power. ... Therefore popular sovereignty is essential to a republic as the people are able to exercise their control via the republic process of choosing a representative. or
Republic: "A state in which supreme power is held by the people and their elected representatives..." Democracy: "A system of government by the whole population or all the eligible members of a state, typically through elected representatives."
