There will be more (much more) from Rick.  (And I’ll keep this spot updated as I find them.)  But just as a start, here he is (with David Savage, Ilya Shapiro, and Lani Guinier) discussing the case on Talk of the Nation.

UPDATE: Rick’s also got one of the entries in SCOTUSblog’s Shelby County symposium today, discussing the odd absence of a definitive standard of review for Congressional action to enforce the Fifteenth Amendment.
