The Center for American Progress has an interactive quiz up: How progressive are you?
I scored 369/400 — unsurprising.
As usual, I had quibbles with the phrasing of some of the questions, like #25
: "The primary responsibility of corporations is to produce profits and returns for their shareholders, not to improve society." That depends on whether it's speaking about the way things are (because US law, as interpreted by the courts, is pretty clear that the answer is yes) or the way I think they ought to be (because, well, NO).
