The authors are Nick Johnson of Fordham, Michael O' Shea of Oklahoma City, George Mocsary of Connecticut, and David Kopel. Given the authors, I expect to see some excellent scholarship on the Second Amendment in this textbook.
Somewhat off-topic, I also learned that Dave Kopel was a lifelong registered Democrat who voted for Nader in 2000. Yet, he has been a staunch supporter of the Second Amendment for a long time and has done a lot of scholarship and writing on the subject since the 1990s. Just goes to show that the Second Amendment cuts across traditional political stereotypes.
