There is a prevalent myth that large law firms, especially old, "white shoe" firms, are bastions of patrician conservatism. This may have been true forty years ago, but the evidence suggests that the vast majority of big law firms are firmly, institutionally, on the Left, whether judged by the political content of their pro bono work, the voting and contribution patterns of their partners, or their willingness to embrace politically correct agendas, such as racial preferences in hiring. Walter Olson offers a case in point: Clifford, Chance honoring heroes of the radical left. AmLaw Daily reports that "Clifford Chance sponsored the book party on the advice of a consultant who advises the firm on art and diversity," the very existence of which should tell you something.
As an aside, given that several of the honorees were PLO propagandists, back in the days when the PLO didn't even pretend to want a peaceful settlement with Israel, I wonder whether the diversity consultants considered the sentiments of Jewish partners and associates. (The PLO folks may or may not have been treated unfairly, I'm not familiar with the relevant story, but merely fighting a First Amendment battle successfully does not make you a "hero" worthy of having your picture in the lobby of Clifford, Chance. Or should I be sending the firm photos of the Nazis who won the Skokie case, for proud display?)
UPDATE: As a further aside, do you think any major law firm is going to honor the Boy Scouts of America as heroes of the First Amendment for winning what I think is one of the most important First Amendment cases of the last two decades, Boy Scouts of America v. Dale? No? Actually, it's almost unthinkable, despite the BSA's overall "mainstreamity". That, combined with Clifford Chance's honoring "heroes of the radical left" for their First Amendment battles, should give readers an idea of how "conservative" big law firms are.
