Let's not kid ourselves, the liberal media is heavily invested in the progressive agenda, ratings be damned. If they can work their agenda into a story, they certainly will do just that.
They aren't pushing the liberal agenda it's a target market. This is where the money is and they know it. There is no news for the sake of telling what actually happened it's all a sales pitch. The more attention they can bring to a subject and thereby themselves the more money they make.
How else could anyone justify a million cable news channels each covering the same stories. .......
