First of all, the only reason Fox News has higher ratings is because it is the one and only network that caters to the right-wing audience. The rest of America has the choice of watching ABC, NBC, CBS, CNN, MSNBC, etc. to get their news and information and therefore their ratings are less, because they share an audience. In other words, if it was just Fox and ABC available, the ratings for ABC would kick the livin' shi%$# out of Fox.
Secondly, the fact that Fox is the only major network that promotes the right-wing agenda should make you wonder the accuracy and the truth to what they spew. Think about it, can it be that all the other networks are wrong and only they are right? I say the fact that there are far more networks that are fundamentally opposite of Fox and that to this day more than 60% of America give Obama a favorable rating indicates that Fox is a lone maverick and only represents a minority of Americans.
