Where in the Bible does it say B. Obama is the Antichrist?

Oprah called him "the One" I believe, and right-wing extremists used that to start nastily declaring he is the Antichrist of the Bible. I don't want any quotes from the Bible that speak generically about this individual; I already know them. If you believe this extremely negative umption, prove it with credible biblical support, not suppositions or reading into the Bible your own interpretations, but actually link Obama with this sinister person.
