McCain reversed himself on torture a couple of months ago when he answered a reporter's question about waterboarding. The reporter asked if he would stop the use of waterboarding if he was elected president. McCain's answer was that he would not rule out any specific tactic for interrogation. This is exactly the same answer that Bush has given for years now.

I'm in the middle of digging around and verifying some sources for what I have read here: http://www.realchange.org/mccain.htm .
But if only half of this is true then I think the heads of Obamas campaign should get their heads around some of the mentioned issues in the article..I guess there will be quite a few points to hit McCain with.

PS: a nice little quote:

Run a set of commercials that show all of the reversals McCain has done in order to gain the nomination. He has completely given up his ideals to win the primary. Show a clip of the "agents of intolerance" comment and then the Bob Jones University speech and the wooing of Hagee. His flip flop on ethanol, his flip flop on gay marriage, and his flip flop on torture.
