If, in fact, Barack Obama does not meet the requirements set out by the U.S. Constitution in Article II, Section I, it would throw this country into a constitutional crisis. Vice President Joe Biden would, obviously, become President Biden. The harrowing part of this taking place is that every appointment made, every piece of legislation signed, and every executive order issued by Barack Obama could, and should, be considered invalid.

Hypothetical: It is proven that Obama was born outside the US. Would all laws and Presidential decrees become null and void?
If he was born in Kenya, or anywhere else except the US, then he fails on either the "Blackstone" (i.e. English common law) or Vattel (Law of Nations) test. If born in the US, then he still fails both, although he fails the Blackstone test by virtue of being a natural born Subject of the Queen of England. (English common law was contradictory, it had all children born in the domain the Crown as natural born subjects, but it also had those born of subject fathers outside the realm as natural born subjects. Thus one cannot apply English common law to "disputes" involving two sovereign nations, since in that case the child be the natural born subject of two sovereigns, which is not allowed even per Blackstone who states that being a natural born subject requires exclusive and permanent fealty to the crown.
Hardly what the founders would have put up with, having just decided to do away with crowns entirely. (What they would think of the Messiah, is probably not printable in this forum).
