I watch em all, more or less, and the people that come down on fox strike me as victimized and vindictive, trivialized and minoritized....angry (aka liberal). Fox reports largely the same things but with a splash of colour the others dont (I have noticed MSNBC trying to be more colouful as of late) and fox definately spins conservative, which is indeed a nice and refreashing treat in the post dan rather, peter jenning, tom brokaw world of news.
And as far as who has a more educated viewer base does not impress me. I do not have a degree and I have spent 20 years working with people who do and by and large, I have not been any more or less impressed with the quality of the person with a degree as opposed to people without degrees. In fact, degreed folks tend to have more maligned points of view and are less open minded about everyday aspects of life.....in my uneducated opinion.
