Are citizens supposed to have control over their government? If so, how do they control it?

We elect senators and representatives for the House. They basically make up what the people who elected them wants, but some are corrupt so they don't really listen to the people. They mainly listen to the people who fund their campaigns. What we do have are the U. S. Constitution and the U. S. Amendments to protect our rights such as forcing the person we elected to do what we want, because if they don't we can "fire" them and elect new ones. (petition)
