The Smoking Gun has some documents showing the John Kerry's demands when staying at hotels when he was campaigning for President. On the first document, there's a list of various foods, and then "Note: JK Hates Celery!" But then on the fourth page of documents, we see that he wants "Vegetables -- preferably organic, not the precut ones" and the first thing on the list of vegetables is "Celery." He's flipflopping on celery.
UPDATE: I can see I'm being unfair. The intro to the documents indicates that the later pages include things for his wife, so the celery is for her. Sorry! And let me add that I have no problem with people making detailed requests like this. His staff should be taking steps to preserve his health and mood. And I'm impressed by how healthy these choices are.
