In their reply to Nunberg they say he's criticising that and not their real method (which involves some complex stats). I think they're happy with their conclusions! Their paper's a UCLA Working Paper (so, not published; it wouldn't count as a publication here, anyway, and I don't think they'd say it had been published). They gave the paper at UCLA (Groseclose holds a "by courtesy" appointment in Pol Sci there), it was apparently very badly received. More than one problem's been pointed out, and there are points their reply to Nunberg can't really overcome, one being the very basic point their "ADA score" method of proving bias is just not very good, another, that it's absurd to measure bias by citation of liberal or conservative sources (that's shorthand; but citation is what they used). The paper's cited by 5 others; one (the only one I've read) has misinterpreted Groseclose and Milyo, suggesting they claim really rather more than they do (certainly more than they should): that's a Stanford Research Paper, by a man who holds a name chair in Political Economy at Stanford. So it goes....
