The headline is "No shit Sherlock" levels of obvious, but I found this bit interesting:

Conservative trust in national news organizations has fallen by 14 percentage points since late 2019, compared to single-digit percentage point drops each year during the Trump era.

So conservative trust in the media dropped slowly but steadily during the Trump era, but then Biden took office and there was massive drop very quickly. It must be the complete 180 the media's coverage took of the presidency the minute Biden took office.
