Al Gore running in '08?

In an appearance in Australia yesterday, Al Gore caused quite a stir in the political world with the comment that he hasn't "completely ruled out running for president again in the future". A Gore campaign in '08 is still very unlikely, but Al may be intrigued by his high poll numbers, still behind Hillary but well ahead of any other Democrat. Al is someone that wouldn't need a long time to build up a campaign structure or name recognition, so it could be awhile before he decides for sure.
