Does anyone know what might cause this? When you enter e.g. [McCain] into Google News, the results showing the word "McCain" are all-lowercase "mccain". [McDonald's] is partly all-lowercase too when queried. It's only a smaller bug but I was wondering why it might be triggered specifically. [Thanks to Dan L. for the tip!]

Sample search: http://news.google.com/news?q=McCain

yes I noticed that a while ago... although not when I searched but when storys about him got on the front page.
It always stuck out.
