This morning the Supreme Court hears oral argument in Hollingsworth v. Perry, the Prop 8 case, previewed in this space yesterday and the topic of much past attention at Cato. Over the past 48 hours Cato scholars and friends have been writing up a storm:

• An editorial in the Wall Street Journal contends that the issue should be left to the political process. In response, Cato constitutional studies director Roger Pilon says the Journal goes fundamentally astray on (among other things) whether the Equal Protection Clause was meant to apply only to some short list of “protected classes,” and whether the Perry and Windsor cases resemble Roe v. Wade (they don’t).
• At Reason, Cato’s Ilya Shapiro debates Jonathan Adler on whether federalism provides a useful organizing concept for the issue. Plenty of debate on that topic at Volokh Conspiracy.
• In articles at Hoover’s Defining Ideas and Ricochet, Cato adjunct scholar Richard Epstein explains why he finds originalism in tension with liberty on the issue, and has some advice for Justice Anthony Kennedy.
• Last chance to register for Cato’s all-star panel tomorrow with former Republican National Committee head Ken Mehlman (NPR profile), Freedom to Marry founder Evan Wolfson (BuzzFeed profile), and Cato’s Ilya Shapiro (AFF profile). You can also watch live online here, and comment on Twitter at hashtag #CatoEvents.
• I’ve got another roundup at Overlawyered noting tomorrow’s panel and other upcoming events, and summarizing a panel on related issues held at Cato last week; I also note the paradox in one recent poll in which a non-trivial number of participants took the view both that same-sex marriage is a right under the U.S. constitution, and that states should be left to go their own ways on whether to recognize it.
