My bad, I hadn't seen anything on the replication of the survey. Do you have a link or something more I can search on? Right now Googling Lott gets nothing but the Brady bunch and their friends crowing over the demise of Lott's credibility.
Here's the original FR post:
http://www.freerepublic.com/focus/f-news/821579/posts from january of this year. (originally linked from instapundit) You have to dig a bit, but following the links will give you a good idea of the origins of the survey controversy (this was before the Mary Rosh farrago hit the media). Seems to me that this was cooked up to coincide with the release of "The bias against guns", Lott's new book, but that IS a bit paranoid.
