I’ve noticed throughout this campaign, by the way, that there are two kinds of Obama supporters: those who have read “Dreams From My Father” and those who haven’t. The ones who have read it tend to be impatient with certain of the stock observations made by nonreaders of all political persuasions—comments like “We don’t know all that much about him” or “I’m not sure who he is, really.” Who he is is right there on the page. Or on the CD: I’ve also noticed that those who have absorbed “Dreams” via the audiobook version, read by the author (who reproduces his characters’ accents), are the most fervent of all.
