I think you forgot “center”. From the perspective of US politics, these are basically the most centrist publications you can get your hands on without penalizing “not reporting false, far-right conspiracies as true or even plausible” as a leftward bias. And if you determine in the context of US politics that undeniable facts are biased, then why on earth would you explicitly choose to plant your center in US politics? MBFC absolutely has a choice in that regard.
