The folks behind "The Obama Nation," the wildly successful but factually disputed new book trashing presumptive Democratic presidential nominee Barack Obama, are casting it as a scholarly, thoroughly researched work.
But its author has left a trail of wild theories, vitriol and dogma that have called into question his credibility.
Jerome Corsi, who rose to prominence as the co-author of a book attacking 2004 Democratic presidential candidate John Kerry, penned another tome asserting oil is a nearly infinite resource that continues to generate naturally, and posted a series of online comments through 2004, including suggestions that Hillary Rodham Clinton is a lesbian and Muslims worship Satan.
In an interview with Politico, Corsi pointed out that he's apologized for Internet postings ripping Muslims and Catholics, and said they don't undermine the integrity of his new book.
"I wrote those to be provocative and I said I would not use that kind of politically incorrect language again, and I don't believe I have," he said.
