Jonathan Adler wrote a very interesting piece on how imbalanced law schools are regarding political ideology and diversity:
The existence of ideological imbalance on law school faculties has been documented in numerous studies. Analyses of law school hiring, political contributions, and legal scholarshipall find left-right disparities. While most law schools have a few token right-leaning professors, these scholars are often relegated to “private law” subjects (e.g., business, contracts, intellectual property), and are less prevalent in “public law” subjects (e.g., constitutional law).
Indeed, most major law schools have fewer conservatives or libertarians on their faculty than can be found on the U.S. Supreme Court.
