More on "Scalito"

Will Baude writes to point out that if you do a LEXIS search for "Scalito," the very first use of the term is in a 1992 National Law Journal article, and it involves the very same "strange locution" in which the term is ascribed to other -- anonymous -- people. This is what the article says:

Judge Alito is described by lawyers as exceptionally bright, but much more of an ideologue than most of his colleagues. It's a trait that has led some to nickname him "Scalito," after the acerbic Supreme Court Justice Antonin Scalia.

Led WHO to nickname him "Scalito"? Has anyone ever used the word "Scalito" besides journalists who think it's a clever pun?

UPDATE: See the second comment below, where a journalist says that he was the first to coin the term. See also this post.
