I just read today that there is a book coming out on this subject next month. With Pre-orders it's already number #2 best seller this week on Amazon and will be #1 by tomorrow.
http://www.amazon.com/Wheres-Birth-Certificate-Eligible-President/dp/1936488299Normally I wouldn't care but the author is Jerome Corsi, Phd. He is the same author who dug up info and outed John Kerry on the swift boat scandal that sunk his presidential bid in 2004.
The book is due out May 17th and supposedly the President already has attorneys trying to stop it's release.
