Daniel Solove's observation that more conservative than liberal bloggers link to Concurring Opinions (a group blog composed of mostly moderate liberals) has set off an unusually acrimonious discussion. Let me suggest that the reaon liberal law blogs don't link to Concurring Opinions isn't that liberals are intolerant of dissent or don't care about ideas. In fact, the issue is simpler: there just aren't that many liberal law blogs to begin with. A quick scan of Concurring Opinions's own census of blogging law professors reveals that the #1 and #4 law schools for prof-bloggers are, respectively, Chicago and George Mason. Ave Maria has almost as many bloggers as Yale. (I recognize, of course, that not everyone at Chicago or even Ave Maria is necessarily a right-wing conservative, but many of these bloggers do seem to be right-leaning.)
Of course, this all leads back to another question: why are there more conservative law bloggers than liberals? Part of it, I would guess, is that - sorry, David Horowitz - law schools just aren't that liberal. Sure, large majorities of most law faculties may identify themselves as Democrats. I continue to believe, however, that law remains a basically conservative profession. True, hard-core constitution-in-exile types may not find legal academia a completely hospitable environment, but that doesn't mean that the decorous moderate-liberals who overwhelmingly populate law faculties would look any more kindly on someone equally far to the left. Law and law schools are always going to be grooming people to enter the power structure (yes, there was once a notion that law could be used a tool of radical activism, but try finding a currently respected professor who believes such a thing). These days, that power structure is conservative.
There are a number of blogs written from a liberal point of view that engage in policy debates and toss around ideas in much the same manner as the Volokh Conspiracy. (To name just a few I've recently started reading: majikthise, Legal Fiction (which, despite its title, is not really a blawg), and Mark Kleiman.) These blogs just don't happen to be written by law professors. I would nonetheless advise those conservatives who claim to be interested in reading liberal blogs with substantive intellectual content to check them out.
