I see it all the time with both CNN, MSNBC and FOX. We're not watching news anymore, only editorials from those who lean one way or the other. That isn't journalism as I remember it. There is a place for editorials and the front page isn't it.
And you are focusing, literally on three television cable stations. There are newspapers, magazines, foreign television, investigative reporting shows, trillions of websites and on and on.
Yes, getting information is hard these days, but that is our fault, not the other side of the political spectrum's fault. We the people want more and more entertainment, faster, brighter, louder, more colorful, more outrageous and all of it within neat little 5 minute segments at most because if there is anything longer we lose interest and go on to the next louder, faster, more colorful thing. At this moment I have my phone on twitter, this computer, one tv on the Yankee game and one on the football game. We want to consume without the repercussion of thought, to see without visualizing context, to hear without listening, and think that when we talk we enjoy the power of wisdom when all we have is nonsensical information that we've never taken the time to understand.
CSPAN shows actual fact. Actual on the floor fact news of what is happening in Congress, the debate, the vote, the bill. A rerun of the 3rd season of Big Bang on TBS will get literally 50 times the rating point, and then we opine the fact that Congress doesn't speak for us anymore.
