The part I do not understand is that Will is supposed to be conservative, but surrounds himself with an 1000% liberal staff?
And way too much clothing for an HBO program.
The point of the show is that conservatives should be smart enough to tell the difference between philosophical conservatism and, as they call it in one episode, the "clown car" that is the Tea Party. Sorkin is asking why Republicans are not doing something about their radicals.
The real target of Newsroom is not the Republican Party though, it is CNN. The fictional ACN is Sorkin's view of what CNN should be, a provider of smart, fact-based, analysis of real news. Instead, CNN has become a traffic cop that makes you stop and look at the car wreck, and it does it on 2 channels. One of the "Tragedy P---" episodes from last season was absolutely brutal on Nancy Grace and CNN's coverage of the Casey Anthony trial. Newsroom takes CNN behind the woodshed almost every episode.
The irony with CNN is that it trails Fox and MSNBC badly until there is real news, at which point CNN spikes. People do trust CNN to deliver real news and not just opinions, but do not care for the manufactured garbage that CNN floats most of the time.
