Obama is among the most interesting people on Earth. The decision to turn his infomercial, or at least his beginning, into a series of portraits of the kinds of people he wants to vote for him, rather than a moment in which he presents himself as a credible commander in chief and leader — which is what Ronald Reagan did so memorably in a half-hour speech a few days before the 1980 election — is peculiar. It’s hard to imagine people wanting to watch this stuff when there are 500 other channels to watch.
