It was good enough for our founding fathers. It is good enough for me. Knowing this is the way that it works, though, ought to make us more careful about who we elect. This is why it so extremely important to know who is running for office and what they stand for. Once elected, you will have little say in how they vote.
Character really is of utmost importance in politics.
Once elected, many of our representatives vote according to their own leanings with only one concern. That concern is whether or not they will be reelected. If their voting wanders too far away from their constituents' values and does so often enough, they fear their ability to win reelection. They know that voters pay attention to them around election time but that most people ignore politics during the rest of their terms. If legislators can vote in ways that reflect their own personal agenda but do not necessarily represent the wishes of those they serve and they can keep the voters in the dark about it, they can have their cake and eat it too.
