These media sources are moderately to strongly biased toward liberal causes through story selection and/or political affiliation.  They may utilize strong loaded words (wording that attempts to influence an audience by using appeal to emotion or stereotypes), publish misleading reports and omit reporting of information that may damage liberal causes. Some sources in this category may be untrustworthy. See all Left Bias sources.

Factual Reporting: MIXED

Notes:  I am pretty sure you have gathered the bias by the name alone.  There is a very strong left wing bias here.  They occasionally produce good content, but they also fail to source sometimes to quality sources.
