We need a screen shot of the old Wiki entry! If anyone can even do that!
McCain most certainly bring this up at the DEBATES.
You can directly see old versions of a Wikipedia page; for instance, the link http://en.wikipedia.org/w/index.php?title=Franklin_Raines&oldid=239081313 takes you to one version of the Franklin Raines page.
The entire history of that page, containing links to all of the versions, is at http://en.wikipedia.org/w/index.php?title=Franklin_Raines&limit=500&action=history.
