Interesting to be around for the birth of a false fact like "the media is right leaning". Overnight you see people start parroting something that's clearly untrue.
Maybe you haven't been paying attention the past 5 years, but there has been a dramatic shift to the right in media. Companies change ownership and the new owners take advantage of the historical left leaning nature of the media.
The magic trick fox news and conservatives has pulled is by being so far right that center/slightly right parties look far left. The normalization of the MAGA movement is evidence of this right leaning media machine.
Look at who owns the "left leaning" media companies. CNN is owned by conservatives.
Joe Rogan, Candace Owens, Tucker Carlson audience dwarf most other channels these days. fox news has almost 3-4 times the viewership of CNN which is the preferred example of a "left leaning" network to balance them.
The rights constant raging against mainstream media is an attempt to distract from the fact that mainstream media is in fact conservative.
