I just started listening to it, but it sounds good so far. Here's the link:

Al Gore's first podcast

EDIT: Gore has an interesting behind-the-scenes take on his GMA interview. Basically, Sawyer had not planned to do another special on his book, but during the commercial break she basically said that she agreed with Gore and wanted to do a more in depth story on his book.

EDIT2: "If I knew now that I was definitely not ever going to get back into the political system, I would certainly say that. But I don't know that."

"I don't think i'll get involved again, but i'm not willing to rule it out."
