Cashill also concluded this, by finding near-identical scenes and passages in Obama's Dreams of My Father and Ayers' Prairie Fire.
Cashill is a genius. He did indeed blow the lid off Obama’s big literary scam/fraud. However, Obama’s true believers [we have one on this thread] would simply say that Cashill is mistaken.
Anderson, otoh, cites multiple sources who confirmed to him that Ayers wrote the entire book, Dreams. That may be one reason Leftist-Progressives don’t cite Anderson’s book much if at all; it makes their hero into a bumbling liar who not only couldn’t write his own memoir—he has pathologically taken credit for this one big accomplishment, which it turns out wasn’t his accomplishment at all.
