For what it’s worth, the New York Review of Books accomplishes this for me. Don’t let the title fool you, they write in depth about current affair topics.
Which is fine if you’re looking for that sort of commentary, but in terms of news it’s not what I was looking for.
The NYRB leans marxism-aware global left, with a heavy dose of academic anaesthesia.
Neither is more "partisan" (I think ideological is likely a better word). You just don't notice it in the Economist because they rarely argue against what already is (since it suits them, mostly, just fine).
As an aside, do you know anything like nyrob that has something equivalent to the economists “the world this week”? Would be neat to see a similar format from two separate ideologies.
