Ronald Radosh claims there is new evidence that former Weather Underground member Bill Ayers ghostwrote President Obama's early memoir Dreams From My Father.Ghostwriting as I understand it can take many forms. The literary issue is unimportant to Radosh and his source -- Ingram's magazine editor and Nazi hunter Jack Cashill -- who are concerned only with placing Ayers and fledgling author Barack Obama together. (Candidate Obama disowned Ayers and denied that they had an extensive relationship.)I am interested in the literary issue. I read and enjoyed Dreams From My Father, and to the extent President Obama disappoints me (a very limited extent, as the Obama Administration has mostly been what I expected), he disappoints me by not being more like the character in the book.
