Media Bias?

It dawns on me that it has been proven beyond any doubt that the main stream media is totally biased towards Obama. I know many of us have said not to trust the polls yet we tend to look at the numbers. Wouldn’t it make sense that if the msm is so biased, polls would be just as biased? So instead of just hoping that the numbers are wrong we do in fact have a basis to believe that the polls have been manilulated to depress McCain voters. Just a thought!
