Jack Cashill whose book HOODWINKED I highly recomment has a fascinating literary analysis of Obama’s memoir compared to Bill Ayer’s memoir at

Cashill summarizes thusly:
The discovery of new matching nautical metaphors from both Ayers and Obama that almost assuredly came from the same source: Ayers, a former merchant seaman.
The discovery of a Bill Ayers’ essay on memoir writing, whose postmodern themes and phrases are echoed throughout Dreams.
A newly discovered book chapter from 1990 that shows clearly and painfully the limits of Obama’s prose style the year he received a contract to write Dreams.
The revelation by radical Islamicist Rashid Khalidi that Ayers made his “dining room table” available for neighborhood writers who needed help.
A refined timeline that shows Ayers had the means, the motive and the time to help Obama when he needed it most.
