More speculation on Gore-this time from Bob Edwards, former host of NPR’s Morning Edition and now at XM:

Bob Edwards: Watch Gore’s waist

XM Satellite Radio’s Bob Edwards has a theory on former Vice President Al Gore’s chances of entering the presidential race: It’s inversely proportional to his waistline.

At a speech last week before the National Council on Education for the Ceramic Arts, the former NPR host said, "Gore was a bit heavy when I talked to him, and it’s long been said of Gore that you know he’s running if he loses weight. People who’ve seen him since my interview tell me he’s lost some weight."

Edwards said if he had gotten a majority of votes but didn’t get to take office, "I would so be running again."
