For instance, I ignore the wall street journal and I have forgotten why (probably the hard server-side paywall). Breitbart basically only writes propaganda, so I ignore it. Fox spins everything to appeal to a specific demographic while trying to manipulate them (e.g. also propaganda). George Will only writes idiocy (I don't know if he honestly believes what he's writing but I get that impression). Krauthammer I read sometimes, and usually disagree with, but sometimes he writes something I end up agreeing with. I think Ann Coulter is either a nutjob or playing a character, and I sometimes read what she writes for a laugh.
Mother Jones is pretty obviously biased in the other direction. Rawstory presents news through a confrontational anti-conservative (or anti-fox) POV. They don't say that, but you can see the framing. I don't usually watch network news, or CNN, or MSNBC, but I didn't notice any bias in NBC news when I watched them. The Washington Post and New York Times are almost certainly progressive, although I think that's a good thing - they investigate injustices and the like that should outrage anyone, and report on them.
One example difference: Where Donald Trump thinks that illegals need to be thrown out (and Mitt Romney called for "self-deportation"), progressives worry that
they're being exploited (NYT expose from last year about nail salon workers - you may have seen it already), for example.
