Washington Post media bias rating is Lean Left.

The Washington Post was given a lean left bias rating that AllSides is highly confident about. Originally established in 1877 as a “four-page organ of the Democratic Party,” the newspaper was eventually sold in 1889, resulting in the abandonment of its Democratic Party allegiance. In recent decades, the Washington Post has been accused of both liberal and conservative biases. A majority of over 7000 community members agreed with a lean left AllSides Bias Rating™ as of July 2016. Among those who disagreed, 66 members gave the newspaper an average bias rating of 58.8, landing it just next to the boundary between a lean left and center bias. These results, in addition to a March 2013 blind survey and a 2005 UCLA study, reinforce our rating for the Post.

The AllSides Media Bias Rating reflects the average judgment of the American people.

The AllSides Media Bias RatingTM reflects the average judgment of the American people. We don't use a convoluted mathematical or artificial intelligence model, but instead have regular people representing the broad spectrum of Americans blindly rate the bias of articles. That produces a fair, verifiable bias rating.

This media bias rating was determined using the following levels of bias verification.

Basis of Rating:

Unless otherwise noted, this bias rating refers only to news articles on their web site, not from opinion pieces or what is broadcasted on TV or radio. The opinion writers from the same media source may have different bias ratings, so individual writers often are rated separately.
