From a reader:

Jonah-
I think this is my new favorite Kerry quote to torment my Democratic friends with. Fortunately, they’re playing it repeatedly on MTV as a promo for one of their asinine get-out-the-vote charges.
Some young guy on the street: “What would be the principal difference between the foreign policy of your administration and that of the Bush administration?”
Kerry: “The principal difference would be just about everything.”
No kidding.
