In the catalogue of life-altering surprises, few compare to the query I received a few weeks ago from CNN/US President Jon Klein: "How would you like to co-anchor a prime time show?" Surely neither drum roll nor punch line is necessary at this point. My co-anchor would be Eliot Spitzer, former governor and attorney general of New York, variously known as the sheriff of Wall Street and the "disgraced" politician who resigned after it was revealed that he had consorted with prostitutes.
