It seems there are two things in play..
The creation of alternate media that exposes their lies and partisanship. It has also eroded their audience to the point of near bankruptcy in many cases.
The MSM has been so blatant with their tactics since 2008 even a two year old can see it. They are either over confidant or desperate.
There is absolutely no reason to believe they are not *both*, simultaneously. They are desperate as they are losing audience on a daily basis, while at the same time, they are over-confident in their assumptions they still have the ability to "shape" events to their satisfaction. They lost their monopoly on the ability to allow or not allow information to the public some time ago, and they have not recovered from that, nor indeed, to even understand the implications of losing that monopoly...
