I think the general consensus of those out there with rational thinking would agree that the network news outlets like ABC, NBC, CBS, and especially PBS are your better options for neutral news (even though conservatives also blame them as well for liberal bias). Obviously, since channels like Fox and CNN are their own niche cable channels, they're going to do what they can for ratings, whether it's Fox being blatantly biased toward the right, or CNN leaning to the left. And of course, as previously said, internet outlets like Breitbart and Info Wars are probably the worst, since they specifically cater to their respective side and nothing else, so clearly they will be one-sided and biased.
As I said, I just rely on my powers of observation to see what's happening around us.
