Dear Bored,
CNN is focused on what people say, and the appearance of the matter. In other words, they are aiming at the shallow viewer. The main issues are ignored. This sells better to the left. Because the ignorant conservative simply does not care who offended whom. According to surveys, CNN has a broad viewers because of the gossip.
PS A good example is the Russian interference story. It is a real story. Just not a partisan one.
