H. Lee Sarokin served as a United States District Judge for the District of New Jersey from 1979 to 1994, and was a Judge on the U.S. Court of Appeals for the Third Circuit from 1994 until he retired in 1996. And more importantly for our purposes, he has just started a blog, appropriately named X-Judge. His first post, The Constitution and a Trip to the Dentist, is here.
