Is the mainstream media answering to Fox News, the Koch brothers and the NY Post now?

So the major networks aren't going to air Obama's immigration speech.  I guess the gutless mainstream media are answering to Fox News, the koch brothers and the NY Post now.  The funny part of the immigration reform bill was that it was supported by Bush Jr. The major networks have never not aired a presidential speech. I wonder if Obama's skin color has something to do with the lack of respect he gets even from  the mainstream media. I guess  Its never guess the gutless media will report about Kim K posing nude again, which along with reporting on Ebola which killed only two people in this country is the only thing they do.
