Then again, if Caroline had been in politics all along, in stead of performing busy work like soliciting donations and editing books for the New York Times (the only book she has ever written all by herself is "A Family Christmas," a collection of poems, prose and personal notes from her family history) she very likely would have made it to Senator from NY a long time ago. Had that happened, Hillary Clinton might be a lawyer these days.
