You're right. I'm not sure how the movie quote made it into my collection of quotes, but somehow it did. I barely remember the movie. Here's the quote from the book. They're pretty much the same message.
"To vote is to wield authority; it is the supreme authority from which all other authority derives -- such as mine to make your lives miserable once a day. Force, if you will! -- the franchise is force, naked and raw, the Power of the Rods and the Ax. Whether it is exerted by ten men or by ten billion, political authority is force."
