Richard Cohen — a commentator I normally loathe, for reasons of interest only to other polico-wonko-dorko-blogo-types — has a good column today about Al Gore’s new movie.

In the meantime, he is a man on a mission. Wherever he goes — and he travels incessantly — he finds time and an audience to deliver his (free) lecture on global warming. It and the film leave no doubt of the peril we face, nor do they leave any doubt that Gore, at last, is a man at home in his role. He is master teacher, pedagogue, know-it-all, smarter than most of us, better informed and, having tried and failed to gain the presidency, he has raised his sights to save the world. We simply cannot afford for Al Gore to lose again.
