Corsi needs to sort out his theory of the birther case. He needs either to show Zero wasn't born in the US and can't claim citizenship from his mother (the original birther case, now thoroughly shot down) or he needs to convince the country NBC requires two citizen parents (the post-election fork of the birther movement press the case only after the precedent is firmly established! LOL!).

But Corsi tries to do both at the same time. Therefore, he's not valid.
DR. Jerry and Joseph have aided Obama in accomplishing a major sleight of hand, a mis-direction. Obama has succeeded in marking out the playing field: making it a case of WHERE, he was born, rather than TO WHOM he was born.
With a foreign subject father, little Barry could have been whelped while Stanley Ann was sliding home at Yankee Stadium, with Yogi Berra as the obstetrician, and the organ playing Yankee Doodle. Born in the USA! Hurrah! Not however, a "Natural Born Citizen."
I fought with them both on G.G.L.. They insisted on playing Obama's game, and now it seems clear that they have lost. So did we.
