Estimating the percentage of mainstream media that is left-leaning can be challenging due to the subjective nature of media bias and the diversity of media outlets.

Additionally, analysis of media content by organizations like Pew Research Center or Media Bias/Fact Check provides insights into perceived leanings of specific outlets.
