Likely a Manchurian Candidate IMHO.  However, I believe the whole birth certificate saga is a red herring.  If Obama was not born in the US, every single intelligence agency around the globe would have known it long before he even considered running for the presidency.  Thus, obviously both the DNC & RNC would have known it as well.    The simple point being, Obama didn't "fool the establishment" with some sort of birth-certificate trickery or forgery.  The establishment knew Obama's history and nation of birth long before he even entered the political scene.  Not a chance.  If he was born in Kenya (or anywhere other than the US), the CIA, FBI, NSA, RNC, DNC as well as dozens of foreign intelligence agencies were well aware long before 2008.
