The American Prospect
Liberal, policy first. Robert Kuttner, Robert Reich and Paul Starr founded The American Prospect in 1990 as a magazine of liberal ideas, and it remains the place where progressive economics is argued in specifics: antitrust, trade, health care, labor law.
Choose it over the more cultural left titles when you want the mechanics of a policy rather than the mood around it. Its reporting on corporate power and government agencies is detailed enough that readers who reject its conclusions can still test the evidence.
