The "news" is only the facts. Either something was done or said or it was not. "An earthquake in Chile" either happened or not, and the news is the report of what happened. Nowadays, the opinions of commentators on what happened, what should be done, what could have been done, what will be done, why it should be done, when, how, etc, is also considered news. Even the disputes between commentators are considered news.
Anyway, I think that FOX had a long history of not being taken seriously, but being very popular. It was also the main proponent and vehicle for the "Obama is un-American and not an American" argument. Did Obama supporters watch? The same is true now for Trump supporters and CNN.
Anyway, it's up to the viewer. No Trump supporter is going to change his vote because of a CNN report. I do agree that CNN spends too much time "shaking their heads" at something Trump did or said. Otoh, FOX and Friends is considerably worse. Even their smug smiles are so syrupy sweet, they're sickening.
Meh, the 60s and 70s were more turbulent. People often blamed their problems on what they saw on tv. Politicians were assassinated. It had nothing to do with the news. Nowadays, people look at the news to get upset or entertained. Enjoy life. One way or another, Trump won't be around forever.
Ps. When I first came back to the US from living abroad, the first thing I noticed was how negative the news here was. There was always the report of some crime being committed. It didn't matter how serious. So, some days, it would begin with "In local news, police are looking for a man who stole a woman's pocket book on 149th street this afternoon." That would be the most serious crime, and the news would go on to report a few less serious ones. So, I just stopped watching the news.
