I think the important thing is that there be plenty of newspapers, with plenty of different people controlling them, so that there are a variety of viewpoints, so there is a choice for the public. This is the freedom of the press that is needed.
Elections are when you have to make a choice. Perfection not often attainable!
CNN is pretty consistently on the left, if you look at their choice of stories, what they play up. It's not what they say. It's what they highlight.
