Dim Bulb: Author Jerome Corsi

WHAT: His newest book, “Where’s the Birth Certificate?,” was released this week, questioning Obama’s eligibility to serve as president. WHY IT’S DIM: In order to keep his material relevant after the release of Obama’s birth certificate, Corsi is now telling interviewers that it is a crude forgery concocted by the White House. Anything to make a buck.

CURE: A few years ago, Corsi was promoting conspiracy theories about 9/11, as well as a merger among the United States, Mexico and Canada. So there is no cure.
