Pollsters Rasmussen, Reuters/CSpan/Zogby and Quinnipiac- Should we be listening?

The campaign for President of the United States has been fought on many fronts. The candidates fight on the ground in each state, while the media gives us 24/7 coverage.
It is clear from the 24/7 coverage, particularly from watching certain cable channels, the coveraged is biased. I have never witnessed the unabashed negative 24/7 chatter currently being directed at Hillary Clinton. To call it sexist is not enough.
