Al Gore has done something interesting, he has hired Roy Keel
to help coordinate and publicize his global warming campaign.
Who is Roy Keel? Only an important aide in his 2000 run, and Howard Dean's campaign manager in 2004.
Gore has a lot to publicize, he has a new movie about global warming and a book coming out soon, and he will continue making big angry anti-Bush speeches. So he has a lot to do and a lot to coordinate...but...he seems to be (re)assembling a political staff and I'm sure his anger will transform into a Presidential run.
I'm going to post a lot more about Gore soon, and how he can march into the White House without breaking a sweat. This is far from an announcement (something he can't do until late 2007 anyways) but it's definitely a step in the right direction.
