When John Kerry was nominated, I said the most important thing he needed was to start articulating a philosophy. Now, everyone outside of the mainstream press realizes this is his problem. NBC's "The Tonight Show with Jay Leno": "You know the difference between 'Friends' and the John Kerry campaign? 'Friends' has a theme." CBS's "Late Show with David Letterman": "Yesterday, in a Cinco de Mayo celebration John Kerry spoke in Spanish, so he has now failed to articulate his messages in two languages."
