Hollywood composer Danny Elfman (famous for "The Simpsons" theme and scores to Tim Burton films) has produced a new ad  for the last week of the presidential race revealing his greatest fear: a President Sarah Palin. Focusing on the possibility that John McCain might not even finish his first term as president if elected due to age and health concerns, Elfman eerily morphs a slow-motion image of McCain speaking into an image of Palin succeeding him. Here is the transcript.

"These are troubled times in a volatile world. With unprecedented crises at home and abroad, we need sound judgment and a steady hand to lead the most powerful nation on Earth. John McCain's age and continuing battle with cancer makes the liklihood of him not completing his term higher than any president in American history. President Sarah Palin. Think about it."

Elfman is seeking support to air the ad in swing states during the final days before the election. Readers are encouraged to visit OurGreatestFear.org, watch the ad, contribute if possible, and pass it on.
