Ground News uses bias ratings from Ad Fontes Media, All Sides, and Media Bias/Fact Check; they rate NPR as Center, Lean Left, and Lean Left respectively.

If you consider NPR to be far-far left then what is Jezebel, The Young Turks, Jacobin, or Democracy Now? That's not even getting into things like Socialist Alternative or pod casts like Chapo Trap House.

Between the ones I listed and NPR are sites like Slate and Vox which are to the left of NPR but not as far left as Democracy Now.
