The parties of the left depend on lies to get elected, and even more so depend on the news gathering organisations to suppress any news that might harm the left. Here is Andrew Klavan making that point:

Here is the first rule of “mainstream” news coverage in America: Whenever the prejudices and illusions of left-wingers are confirmed by an individual incident, the incident is treated as representative; when those prejudices and illusions are contradicted, the incident is considered an aberration — and treating it as representative is deemed hateful.

You would think that everyone knew that, but not everyone does. You would think that everyone who does know that would discount any news source from the usual sources as tainted, but not everyone does that either. The left and the media are now as one. The media know the power they have and they are filled with those who are prepared to lie and distort every message they write and print to perpetuate the left in power.
