I certainly don't trust in the least the right wingnuts on Fox News (or more rightly Fox Opinions. I don't know how they can use the word News with a straight face). The same is with the left wingnuts on MSNBC who at least don't include the word News in their name. You know you are getting something geared more for entertainment when you tune in to them.
The "major" news networks (ABC/CBS/NBC) ... ahem ... I think they lean to the left, some more than others, but generally if I had to get something as close to the facts as possible I would would take what they report over the loons on the cable networks.
I think if you work for any of the cable "news" networks that they make you drink out of a separate fountain spiked with some sort of chemical to affect the brain.
