Yes, Tucker, Hannity, Pirro and others are conservatives but they also feature Juan Williams, Marie Harf, Chris Wallace, Jessica Tarlov and others who aren't conservative. Chris Wallace is particularly liberal.
CNN used to have a couple conservatives on a semi regular basis but they have all been driven out. Oh, right, they still have one 'conservative' left, that slob Ana Navarro LOL
Although pretty sad, Fox still is far less of an echo chamber then CNN or MSNBC.
