The left is still pushing it.
The MSM is not liberal because of any government regulation, it is liberal because the people who own and control it are either liberal themselves or choose to push the liberal agenda for other reasons. Their is nothing stopping a conservative, or group of conservatives, from buying any MSM business and making it a conservative mouthpiece. There are rumors of the "fairness doctrine" being reenacted but I highly doubt this. For now, liberals can own and control NBC or CBS and make it a propaganda arm of the DNC, a moderate can own and control FOX and make it "fair and balanced", and a conservative could own and control any media outlet they want and make it the voice of conservatism. Conservatives, for whatever reason, have chosen not to do this. This is no reason to bash the liberals for being smart enough to understand the importance of controlling mass media to push their agenda. You put your money up and you make your choices. That's capitalism and that's freedom.
