Update: I want to add this link to NRO where Peter Wehner describes how effective the ads making fun of Obama and his celebrity are.
The bottom ad is funny and it does set the perfect trap to Obama in Denver. There will be Obama, in this big stadium in front of his adoring throngs. The entire thing is planned to be bigger than life and Obama is some sort of mystical change agent that we have all been waiting for.
Which is exactly what the ad above makes fun of.
I don't know who is in charge of these things over at McCain's, but they are geniuses.
