I watch FNC all day long right up until 1-2 am everyday. If they are not significantly biased, there ain't a cow in Texas. Not only do they have a bias, they are biased by omition. Example; If there is a scandel involving a Dem (Gov McGreevy NJ, for example)they will play it all day long. If, on the other hand, it involves a Rep, you may never hear about it or at the bare minimun. Example; Tom Delay and the investigation in relation to his involvement in an industry in his domain that manufactures the gas additive MTBE. When Connecticut Governor John G. Rowland resigned due to a major scandel, barely a word was mentioned about it on FNC. It is so blatantly biased, it would be like listening to Rush L to get your news, "Fair and Balanced"! LOL, What a joke! Hitler would have been ecstactic to have such an organization dedicted to spin. Even the weatherman has political spin.
However, they are the National Inquirer of news channels. They are far more interesting to watch, spin or not, than CNN or the rest.
