George Packer's recent article in the New Yorker, "The Choice", is a great summary of the key issues between Clinton and Obama. After a summary of one of Obama's speeches, he leaves us with this paragraph:

Obama spoke for only twenty-five minutes and took no questions; he had figured out how to leave an audience at the peak of its emotion, craving more. As he was ending, I walked outside and found five hundred people standing on the sidewalk and the front steps of the opera house, listening to his last words in silence, as if news of victory in the Pacific were coming over the loudspeakers. Within minutes, I couldn’t recall a single thing that he had said, and the speech dissolved into pure feeling, which stayed with me for days.

Is he describing a political candidate or a drug?
