Not very often anymore. I can't find a channel that is completely objective. They all want you to be on their political side.
You're certainly right about that observation. One sidelight to that trend which I find somewhat amusing in the midst of a more serious problem--the lack of objective newscasting--concerns the need that is felt by some of these channels to SEEM unbiased.
Several of them have taken to announcing, with apparent pride, that they are
not partisan and intend to present the news without either liberal or conservative interpretations.
And then they proceed to give you the same old slanted newscasts, sometimes with retreaded newscasters who are well-known to be mouthpieces for one particular political party or ideology, regardless of which network currently employs them.
