USSC Speculations

While some people are talking up Wilkinson for the Supreme Court, I'd be interested in hearing what they have to say about his opinion in Simpson v. Chesterfield County Board of Supervisors, which held that it was permissible to bar leaders of non-monotheistic religions from the list of those eligible to lead legislative invocations. In my opinion, Marsh was wrongly decided, but this application of Marsh is deeply troubling to me, and it should be equally troubling to anyone who genuinely cares about religious liberty.
