Almost, but not quite. Huffington Post at least "occasionally" criticizes the folks on the left, while Fox is pretty much state-run TV at this point. I try occasionally to tune in Fox News, just to hear what they're feeding to the right, but I never make it more than 5-6 minutes before I have to turn away. I kept expecting to hear some Starship Troopers propaganda come across "Service equals Citizenship...would you like to know more?"
With Huffington Post, after 5-6 minutes of browsing, I come away thinking "Quit whining already, ya liberal pussies!"
CNN, CBS, NBC, ABC and a few others seem "middle" enough to suit me....
Splitting hairs, but yeah, you essentially laid out the gist of it. CNN is bias too, but it's not as obvious.
