I am grateful to Professor Baum for his very generous review of Dred Scott and the Problem of Constitutional Evil. I am also grateful that Baum in his review and his response to mine highlights the normative significance of his research on judicial audiences. Dred Scott v. Sanford may have been wrongly decided, Baum suggests, because antislavery justices, not being able to predict the actual impact of their decision, should simply have freed Dred Scott as a matter of simple justice. In fact, all five southern justices in Dred Scott v. Sanford did simple justice by their light. More important, however, Baum is now self-consciously exploring central questions of American constitutionalism.
