From the American Thinker:
Now, thanks to Jack Cashill, the literary mask has been removed. Obama is a literary pretender. Case closed. The evidence is overwhelming that Bill Ayers ghost-wrote Dreams from my Father, the book which established Obama's pose as a brilliant writer (and therefore a fine mind, in the estimation of many). The stylistic resemblance between the Dreams and Ayers' work is stunning. Now we know, thanks to Chris Andersen's new book,that Obama hit a brick wall trying to fulfill his contract to produce a book, and shipped off his notes and tapes to Ayers. That is the classic description of a ghost writer's assignment. And it completely fits the theories Cashill had inferentially reasoned from the data of his literary studies.
The revelation that Chris Andersen had two separate sources means that this fact meets the journalistic standard of reliability, provided by a respected, established bestselling author. Obama's dismissal of Ayers as "just a guy in the neighborhood" has been shown to be an outright lie.
