Well, it has been used consistently by the media, and I think people generally believe its polls. Of course, it has had some mistakes in the past: "Gallup polls are usually accurate in predicting the correct outcome of the current United States presidential election. A notable exception is the 1948 Thomas Dewey-Harry S. Truman election, where nearly all pollsters predicted a Dewey victory. The Gallup poll also inaccurately projected a slim victory by Gerald Ford in 1976, where he lost to Jimmy Carter by a small margin." http://en.wikipedia.org/wiki/Gallup_poll

Of course not, no polls are. But they are not meant to be. The purpose of polls is to get a general idea based on a sample. It could be totally wrong however as you might have picked a "bad sample". Hence why it's generally better to take from two or three similar polls instead of just one.
