The campaign has posted a hard-hitting 40-page rebuttal of assertions by author Jerome Corsi.
Corsi, who co-authored a book targeting John Kerry during the previous presidential campaign, catalogs various allegations that have haunted Obama on right-wing blogs and anonymous e-mails.
Those assertions question Obama's religion, brand him a dangerous radical, and suggest there's a black rage hidden beneath the surface.
Corsi also dwells on Obama's mother marrying Obama's African father and later marrying someone from Indonesia - whom Corsi describes as "a second man of color to be her mate." The campaign says the description is one of many examples of Corsi's "offensive language" in the book.
The campaign's rebuttal is entitled "Unfit For Publication." The title is a play on the anti-Kerry book called "Unfit for Command." The rebuttal is being posted on the campaign's rumor-fighting Web site, FightTheSmears.com.
