"CNN is pretty consistently on the left, if you look at their choice of stories, what they play up. It's not what they say. It's what they highlight"

Rupert Murdoch is suggesting that CNN is prejudiced in the direction of the left-wing in their reporting. He is not saying that CNN is lying or being deceitful, but rather that they are selecting to concentrate on tales that are more probable to be of interest to a left-wing audience. He is indicating that CNN is absent a well balanced view of the information, but rather is highlighting stories that are more probable to be of passion to a left-wing target market. This could be seen as a criticism of CNN's coverage, as Murdoch is recommending that they are absent a balanced view of the news. However, it might additionally be seen as a recognition of the reality that various target markets have various interests and that it is necessary for news outlets to cater to those interests.
