One reason is because he is not a good "politician." And I say that with the highest regard for him, because to me a "politician" is the label I put on someone who is just part of the status quo fabric of this corrupted political system. Someone only out for their own benefit. Someone who plays the game at others' expense. Someone who does not see any higher purpose in what they do. So no, Al Gore is not a good "politician" and that is really a good thing.
