In what alternate fuckin' reality do you live in where Republicans have dominated the Big 3, NPR, Newspapers, wire services, etc etc etc?
I will not argue whether or not NPR is "liberal" or "democrat" or whatever. I will concede your point that it is NOT conservative; however, I know nobody who listens to NPR, not even myself (which is why I will not argue your assertion there).
Newspapers are, or at least used to be, "big", but your assertion falls flat on its face there. One example is that The Washington Post, a very major newspaper, was purchased semi-recently by a conservative. Numerous other newspapers are also owned by conservatives. Your point falls flat here.
Wire services are essentially fact repeaters and in fact, appear to have a conservative bias to the facts that they look at and reveal. It is other news organizations that do the editorializing.
Ultimately, you will have to provide a much more coherent argument if you would like anyone to listen to you assertions.
Have a nice day. :)
