Yesterday law professors Erwin Chemerinsky (Duke) and Peter Edelman (Georgetown) released a letter signed by 160 law professors opposing the confirmation of John Roberts (coverage here). The real news is not that there are so many law professors on the letter, but so few. Given that the clear majority of legal academics lean to the left, it is notable that only a small fraction of the nation’s several thousand law professors were willing to sign on. (It may also be worth noting that only three months ago Chemerinsky said he thought Roberts would be a relatively non-divisive nominee, as compared to some potential alternatives.)
