Thanks to Matt Adler, Douglas Baird, Omri Ben-Shahar, Lee Fennell, Barry Friedman, Jake Gersen, Aziz Huq, Dan Kahan, Saul Levmore, Anup Malani, Tom Miles, Richard McAdams, Rick Pildes, Eric Posner, Jennifer Rothman, and David Strauss for helpful conversations and comments on an earlier draft, and to workshop participants at Loyola Law School Los Angeles, The University of Chicago Law School, and New York University Law School’s Constitutional Theory Colloquium. The latter workshop had to be cut short, and dramatically so, but Rick Pildes and David Golove made sure that I benefited from the participants’ generous attention to the Article. Hanna Chung and Daniel Roberts provided excellent research assistance. Mistakes are mine.
