How do people enact power?

Thank you

I think the problem might be in the definition of "enact."

http://www.merriam-webster.com/dictionary/enact

The question would probably be better phrased like this: "How do people use power?"

Or maybe this: "How do people make use of the power they've been given?"

The sentence is still very general, and it's not clear if "people" are private citizens or public officials.
