By far the worst actor I've seen is (old media) Rush Limbaugh. It's hard to believe that Rush could believe that America faces any threats (e.g. war, crime, economic, environmental) other than the "Democrat party." You'd imagine that he wants to see a system more like Japan (liberalism with one party) or China (one party, no rights, no dissent.)

More generally I see the problem of "spamming the agenda", combined with the "if it bleeds it leads" tendency of the media.

Before Trump ran for president CNN's ratings were in the toilet, and it lumbered on between school shootings and MH370. To report on things like that you might have to take the Redeye from Atlanta to a flyover state, but today you can sit your ass in Atlanta or Washington DC and just cover 'what trump said', and 'what somebody said about what trump said'.

Since the election, the news has seemed to be "broken" in the way that a "clock" breaks. Arstechnica's Dealmaster always has a sale on Amazon Fire devices, Anker power banks, Xbox Gold, and whatever craptop Lenovo has a surplus over. The banner on CNN often seems to go unchanged for weeks. (e.g. "TRUMP WANTED TO FIRE MULLER")

COVID-19 was the first real news in a long term, but there is an obsession about "what trump said" compared to the other 300 million Americans. Trump doesn't really care if it is good or bad news, he just wants to be in the news, and if he held a press conference and nobody came, that would bring him to tears.

Similarly there is always some article pushed by a right wing group that says there is too much occupational licensing in the U.S (maybe true, but the same editorial turns up every month as if it was fresh) or that there is a trade-off between economic efficiency and inequality. (e.g. the evidence is that if you have too much inequality people tilt the scales, rich people buy T-bills depressing interest rates, and try to keep the action for themselves and their children... One of those reasons why Stalin invented the Purge)
