In review, Daily Kos reports news through bloggers, who generally lean strongly left. There is moderate use of loaded language in headlines such as this: Voting Rights Roundup: Michigan GOP attempts to sabotage redistricting reform by withholding funding. This particular article is properly sourced to credible mainstream media outlets and newspapers. In some articles there is very strong use of emotional wording such as this: This is how Republicans get away with their lies: The media lets them do it, again and again.
Most articles are written by community members with the rest written by staff members. Editorially, there is very strong left bias with mostly positive articles in favors of left leaning positions and denigration of conservatives. In general, all information tends to favor the left and most articles are sourced, however some of the information written by community members is not vetted by Daily Kos and may contain factual errors or extreme bias.
A factual search reveals that the Daily Kos has failed a few fact checks.
President Trump posthumously pardoned notorious 1960s criminal Charles Manson. – FALSE U.S. President Donald Trump brandished his middle finger as a gesture of disdain, disrespect, or anger towards an astronaut who publicly corrected him. – FALSE Says video shows Mike Pence quoting the Bible as justification for “Congress not to fund Katrina relief effort.” – PANTS ON FIRE
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. (5/13/2016) Updated (D. Van Zandt 12/11/2019)
