Gee I wonder why? According to Politifact 59% of Fox News is mostly false or worse but yet republicans seem to believe Fox hook, line and sinker. Why is that? MSNBC is is not much better, 43% of that channel is mostly false or worse. CNN comes in the best with 22% mostly false or worse, but still that is not very good.

You forget that truth and falsity are not the only questions. The media also decide what news is to be reported and if so, how it is to be presented, shaded and or exaggerated. The liberals just avoid or downplay news with places the administration or party in a bad light. Politifact itself is liberal and its employees or agents make a decision which "fact" will be measured in deciding those alleged percentages. Read the fine print on its page.
Please notice that 45% of democrats do not even have a "fair"amount of trust in the media, including the liberal biased media.
Since bias is usually apparent to those who are willing to see it, it is the bias which drives the public to distrust. More people trust Fox because it the only one which is friendly to Republicans. By ruthlessly promoting the liberal democrat agenda, the liberal press created the opening for Fox to fill.
