Controversial Comparison

(Fox News) - The John McCain campaign is hitting back at Madonna after the pop star compared the Republican presidential candidate to Adolf Hitler during a concert in the United Kingdom. Madonna's swipe came Saturday when she performed a song entitled "Get Stupid." McCain's image was flashed alongside pictures of Hitler and Zimbabwean dictator Robert Mugabe, along with images of destruction and global warming.

McCain spokesman Tucker Bounds said, "The comparisons are outrageous, unacceptable and crudely divisive... it clearly shows that when it comes to supporting Barack Obama, his fellow worldwide celebrities refuse to consider any smear or attack off limits."

Toward the end of the performance, pictures of Al Gore, Mahatma Gandhi and former Beatle John Lennon were flashed alongside Barack Obama's image.
