Obama doesn’t write his books. Take it up with the ghostwriter.
There's another great article on this subject by investigative reporter, Jack Cashill, in American Thinker:
How Obama Himself Made More Than 'Enough Money'
Excerpt from the article:
As Andersen tells it, Obama found himself deeply in debt and "hopelessly blocked." At "Michelle's urging," Obama "sought advice from his friend and Hyde Park neighbor Bill Ayers." What attracted the Obamas were "Ayers's proven abilities as a writer." Noting that Obama had already taped interviews with many of his relatives, both African and American, Andersen elaborates, "These oral histories, along with his partial manuscript and a trunkload of notes were given to Ayers." The result was Dreams From My Father.
BTW, Obama made millions off of "Dreams From My Father". I wonder if he shared any of that with Ayers?
