This column ran in the Wisconsin State Journal, Madison, on December 9th, 2007. The fact that it is a "rerun" does not negate its inaccuracies--no such caveat appeared in that publication.
I suggest readers check into Paul Krugman's New York Times column of November 9th of this year--exactly a month ago. Krugman notes that Rudy Giuliani has used these same "statistics" on cancer survivial in the English National Health Service even though they have been refuted.

Moreover, the pro-business Cato Insitute and its Canadian clone, the Fraser Institute, can hardly be viewed as objective in this matter.
As a matter of journalistic ethics, you should send corrections and clarifications on Chapman's column to every paper carrying it, with the directive that they publish those corrections.

In my earlier E-mail concerning Steve Chapman's column on Canadian Health care, I made one error. The Wisconsin State Journal did, in fact, print that the column had originally appeared in 2005.
The disclaimer was printed at the end of the column, while it was at the beginning of the column on the Creator's Syndicate web site.
However, my criticism of the content of the column, and its apparent misrepresentations--not to mention the fact that it was outdated--still stands.
