My rental car out here in the Southwest came equipped with XM satellite radio. I've been spending a lot of the time listening to the "POTUS '08" channel, which focuses on the upcoming presidential election. I got to hear a town meeting held by Barack Obama, whose articulate, thoughtful, and knowledgeable answers to foreign policy questions from the crowd elevated him considerably in my estimation. In contrast, this was followed by a Rudy Giuliani stump speech in Tampa, in which it was clear the former New York mayor is now far less than the man I came to admire in the fall of 2001; instead he has adopted every partisan bullet point possible rather than offering the maverick leadership we saw in a time of crisis.
