Continuing with our ongoing Defamer Decides 2008 political coverage (splashy logo forthcoming just as soon as we figure out how to work out another Photoshop 30-day free trial), we now bring you this new ONE campaign TV spot featuring Hollywood's most likable superstar and enviable nape-haver Matt Damon. The ad features the pedostache-free actor star soberly addressing the camera about their poverty-combating efforts. Fans should be warned, however, that the strange voices that soon emerge from Damon's lips are not the result of any multiple-personality disorders, secret hormone treatments, or Satanic possessions.

Rather, Damon was transformed through the magic of A/V editing into the comely mouthpiece for a wide variety of American voices, "among them Michelle Obama, Cindy McCain and Mayor Bloomberg." It's an effective gimmick, if a little unfair to John McCain, who now can't help but hide his disappointment every time he rolls over in bed to the sound of his wife's voice, only to find a smiling Cindy instead of that dreamycakes actor from the Bourne movies.
