Related to the post below, Steve Hayward has a chart reflecting annual polling over the past 29 years on the question of whether people have a "great deal" or quite a lot" of confidence in newspapers and television news.
It is hard to make elected governments work when trust in news sources is this low. So I do a bit of 'horseback' extrapolation as follows.
Roughly half the electorate votes for each major party. If zero Republicans trust papers and TV news, then something like 2/3 of Democrats don't trust them either. These Democrats must understand they're being lied to at the same time they're reading stuff designed by the legacy media to please them.
