Wingnut Conspiracy Theory of the Day

This is the nuttiest/juiciest thing I've heard all day (perhaps all week), via some fringe wingnut named Jack Cashill. His theory is that Bill Ayers ghost wrote Barack Obama's acclaimed first memoir, Dreams from my Father.

Evidence continues to mount that Barack Obama had substantial help from Bill Ayers in the creation of his 1995 book, Dreams From My Father, a book that Time Magazine has called “the best-written memoir ever produced by an American politician.” The evidence falls into five general categories, here summarized:

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.
