Bubba's Big BookAfter years of writing, former President Clinton finally delivered 'My Life' to the publishers last Thursday.Now that editors have the text, says spokesman Jim Kennedy, 'the publishers have given the president his life back.'He's now getting ready for the book tour, where writers cramp from writing the book will be replaced by the writers cramp from autographing it.Friends say pulling together the 992 page text wasn't easy: One said Clinton wrote 800 pages before he even reached the subject of his presidency.
