Obama debunks Corsi smears

The Obama campaign has released 41 pages of facts debunking Jerome Corsi's attack book, "Obama Nation." The pdf file is here. And Rachel Maddow, subbing for Keith Olbermann tonight, does a story explaining just how the book hits #1 on the NYT bestseller list. Hint: it's basically right wing groups and conservative organizations buying the book in bulk to give out.
