That is the theory I go with also.
If his children were adopted illegally, then he has no business on the court. He supposedly knows the law, he should have obeyed it.
I am not going after his kids here, I am only saying that if the facts come out that this is his reason for going with Obama then the man should be removed from the court.
I PRAY that someone looks into it and tells me they are LEGAL, then I can just DEPISE him eith no guilt!! :)
