The maintream media skews polls to discourage Republican voters and has done it for years.
Ann Coulter warned in her book Slander in 2003 that the far left mainstream media outlets always use polls to push their agenda.
Polls can be skewed by selecting an unreasonable sample size, by asking lead up questions or by selecting more of a sample population on one side of an issue to achieve a desired result
A good example of the media trying to shape a vote occurred 36 years ago today.
In a Gallup poll released on October 26th in 1980, two weeks before the election, Jimmy Carter was leading Ronald Reagan 47 – 39.
Two weeks later Reagan won in such a landslide that Carter conceded before California was counted.
