You aren't represented. You are given a limited choice to choose from to "represent" you whether they truly hold your beliefs or not. Then you are completely at their mercy for whether or not they actually follow through with their promises. Even if they did follow through, the others who oppose aren't represented.

One of the core principals that makes government evil is that, at least in the U.S. , it is based on delegating rights and abilities to someone that you don't have yourself. The laws after the fact are irrelevant.
