When Will Al Gore Endorse If He Endorses?

Those in the know -- and there is no one really in the know -- say that they don't expect the former vice president to have anything to say about his 2008 presidential endorsement until after his global warming forum in New Hampshire. (He's co-hosting it with Arnold Schwarzenegger and John McCain and others).

The date, at this point, is TBD.

But, obviously, uh, soon.
