If Elena Kagan is confirmed, the Supreme Court will have six Catholics, three Jews, and, for the first time in history, not a single Protestant. That might not seem as important as it used to, but Ed Kilgore of FiveThirtyEight decided to take a quick look at the court's historic religious makeup. At present, Catholics, who make up only about a quarter of the population, are certainly overrepresented.
But historically, they've been underrepresented—the current six are half of the Catholic justices who have ever served. Even more underrepresented, historically, are Baptists (three justices), Mormons (none), and, of course, atheists (none). “If there is a lesson,” Kilgore concludes, “it's that this is no longer a Protestant Nation, and that 'fair' representation of religious communities takes some time.”
