They have been attack dogs of one political party or the other. But its always been this way. Social media ( especially twitter ) has shown people that journalists are political actors, not dispensers of "truth". They are part of the power structure, not a counterweight to the power structure.
At this point most newspapers should just be part of the democratic, republican or intelligence agency because that's all they are.
I can almost guarantee that most of the people here attacking greenwald and partaking in the downvote brigade are news employees or members of a particular political party. It's hilarious.
