Look, a key reason CNN and MSNBC have shifted is the GOP threatens to cut them off from access to lawmakers and, just as importantly, from news sources. The media trades on information and withholding it from the media is like withholding crack from an addict. The GOP is willing to play fascist hardball. We don't have access to power as our carrot/stick, but we do have news sources to withhold as well as the legitimacy cover they need to pretend they're "journalistic" news outlets.
The simple fact is that big media, as presently constituted, is our enemy. When and where do we draw the line and say enough?!
