I think people are just losing interest in general. Losing 18% of viewership, while the least of the losses, is still nothing for them to be happy about. I quit watching any of them months ago.
I'm hoping that most people, across the political spectrum, are realizing it's all just hogwash propaganda. That it's the clowns on "cable news" and other media outlets that are driving the wedge between us. Maybe we Americans don't really hate each other so much after all?
That's what I hope, anyways.
