An analysis of the product indicates a clear bias. The left-leaning biased organizations far outnumber the right-biased ones.

since the moment the Democratic Party, led—dragged, really—by Bill Clinton, itself shifted right to form the center-right neoliberal consensus of the early 1990s.
In most western democracies, it's the center which needs to be allied with the administration in order to govern.
The shift isn't to the right. The failed embracing of Identity Politics and Intersectionality by Hillary was the final stage of a massive shift of the Democratic party in the center under Bill Clinton far to the left. Much of that was overseen by Obama.
Throwing out due process and freedom of speech -- individual rights -- is about as radical-left as you can get. In years past, such specific shifts would have been widely recognized as basically going as far left as Mao. It's basically throwing out the fundamental ideological basis of the United States. Now people are trying to convince people that this is "normal" and wanting such foundational individual rights is "shifting far right." Sorry, but anyone who remembers 10 years ago with a clear head can recognize this as a retcon of US history.
No, it's not. The lions share of media workers may have left-of-center leanings, but media firms aren't coops, so that doesn't actually matter; old media corporations are not owned and run by leftists, or even left-of-center-ists.
The mainstream media may be getting increasingly distant from the Republican Party by standing still (or, at least, moving to the right more slowly), politically, while the Republican Party continues the sprint to the far right that it's been doing since the moment the Democratic Party, led—dragged, really—by Bill Clinton, itself shifted right to form the center-right neoliberal consensus of the early 1990s.
(I call this response an “Overton Slingshot”, because while the tactical move to the right by Dems may have had short term electoral benefits for those left of center in getting slightly less conservative Democrats elected over Republicans—though whether it had any tactical value is itself highly debatable—it definitely was a long term disaster for them in the way it shifted the Overton Window.)
