Mitt Romney loves it, too:

"that was the best ad that the McCain campaign could have ever hoped for, because listening to Hillary Clinton and Barack Obama talking about experience in a national security crisis is like listening to two Chihuahuas arguing about which is the biggest dog. When it comes to national security, John McCain is the big dog, and they are each the Chihuahua."

Hey Hillary, John McCain is looking for a VP. Maybe you should apply, since you've spent so much time helping his campaign.
