The difficulty that the left-media are encountering is that while they constitute the vast majority of the total national media, all of them are competing for the same 50% of the audience, the left half of readers and viewers. Conservative media are a much smaller percentage of the total media, but they occupy a less competitive space appealing to the right half of the population. It's especially hard for CNN since they have historically tried to position themselves as a centrist bipartisan space so as to be the place where Republicans as well as Democrats turned when important news events were breaking. I don't think that CNN is going to attract nearly as many Republicans now that they have started wearing their hostile partisanship so obviously on their sleeve. So as they complete their editorial swerve left, they will find themselves competing along with all the rest of the MSM for an inevitably smaller share the left half of the population.
