The way Fox is more fair and balanced is not which way they lean but what stories they choose to run..
Most of your ABC,NBC,CBS,MSNBC types only show stories that don't put Obama in a bad light and if they have to show one of the stories it is only for a short time.
Fox hold republicans feet to the fire as well as Dems, other networks only want to hold Repubs feet to the fire for a long time.
Fox has opinion shows.. Fox and Friends, Oreilly , Hannity, are Conservative shows and if they could make money with a Liberal show they would have one but nobody watches that stuff for the most part. Their News at 6 pm is Non Bias and Shep Smith is a Liberal himself and shows it from time to time but he is not what I would call Biased in his reporting . Now go to MSNBC if you want to see Hardcore Bias... they are sickening but thats what they do and they have a small audience...
