biden campaign by reporters jonathan allen and amy parnas. the book is called "lucky: how joe biden barely won the presidency." this is such a great -- quote, jim clyburn had heard enough, or really not enough. the house democratic whip pushed him out of its seat at charleston gillard center concert hall. he dashed for the exit with the urgency that france recognized as a 79 year old man's hurry to find a restroom. but clyburn didn't need to use the bathroom. he needed to find joe biden, and fast, before the end of the commercial break during that nights presidential debate. it was february 25th, four days before the south carolina primary and biden was blowing it again. almost an hour and 45 minutes had passed in the debate already and biden had not mentioned the one promise clyburn had said would nail down black votes in south carolina throughout the rest of the primary and in the general election. clyburn was shocked, but not stunned. he made a beeline for the backstage area.
