Overall, we rate CNN left biased based on editorial positions that consistently favors the left, while straight news reporting falls left-center through bias by omission. We also rate them Mostly Factual in reporting, rather than High due to misleading information presented by guests as well as a few failed fact checks by TV hosts. However, news reporting on the website tends to be be properly sourced with minimal failed fact checks. (5/16/2016) Updated (D. Van Zandt 01/30/2020)
Overall, we rate the Daily Kos strongly Left Biased based on story selection that almost exclusively favors the left. We also rate them Mixed for factual reporting due to non-vetted content as well as a few failed fact check and misleading claims.
