RHODES SCHOLAR REX MURPHY on Al Gore and Keith Olbermann’s smarts. “As Gore’s star pales and recedes, and as the furious sanctimonies of global warming meet resistance, perhaps fading Al sees something of a mirror image in the fall of Keith. And perhaps both of them sense that each of them has had his moment, that this moment is past, so maybe the only fun left is to join hands and mutually console for what little of the gig remains to either of them.”
