Thank allah for “Iron Chef.” To put all the ridiculous disillusionment with the Big O in perspective, it was only a year ago that the White House was occupied by a useful idiot whose idea of a good meal was a pretzel and an O’Doul’s, with his wife nowhere near to catch him as he fell. Now half the political wisecrackers I follow are Tweeting on Mrs. O and her stronger-than-Alice crusade to get Americans to eat better. If the tradeoff is a little orange tainting the White House, I guess it’s worth it.
