Over at SCOTUSblog, I posted a Q&A session with Andrew Martin, who is a former guest blogger on ELS and current professor of law and chair of the political science department at Washington University. I interviewed Andrew about the potential academic and non-academic uses of his Martin-Quinn scores of judicial ideology. I also asked him a number of questions about his new co-authored piece on ideological drift of Supreme Court Justices, see here, with Lee Epstein, Kevin Quinn, and Jeffrey Segal, which is forthcoming in issue four of the Northwestern University Law Review. As you may know, the ideological drift piece has been cited and discussed in the popular media and it triggered interesting responses from such excellent scholars as Ward Farnsworth, see here, David Strauss, see here, and Stephen Burbank, see here. Linda Greenhouse of the New York Times even weighed in the on the issue here.
