People filter information based on their own belief system. For example, people who watch Faux News on a regular basis tend to be more conservative in their political beliefs. No problem (it is what it is).
However, despite it's political flavor (along with the countless number of daily editorial decisions supporting a specific agenda), should a media corporation (radio, television or print) be allowed to make direct campaign contributions? Could this sea of corporate money interfere with the political process? Do unlimited 527 campaign donations to a specific candidate endanger the foundations of a Free Society? Do you ever ask yourself, "why do I believe what I believe?" And yes, Karl Rove is on the payroll of Faux News.
"My choice early in life was either to be a piano-player in a whorehouse or a politician. And to tell the truth, there's hardly any difference."
~ Harry S. Truman
