Two articles critical of GOP candidates McCain and Palin appeared in online editions of the Chicago Sun-Times and FOX News respectively. Both articles linked to 'error' messages within minutes of their publication.
The headline of the first story to 'disappear' was EBERT: JOHN McCAIN'S BAD MANNERS. The CST error link can be found at http://www.suntimes.com/news/politics/1190154,ebertmccain092808.article
The FOX News headline was CONSERVATIVES BEGIN QUESTIONING PALIN'S HEFT, and links to an error message at http://elections.foxnews.com/2008/09/28/conservatives-begin-questioning-palins-heft/
