The implication, to this non-attorney, is that a bastard child cannot be a natural born citizen. In many societies and their religions, Judaism being just one of them, membership is carried by the mother, because she can usually be associated with the child. Citizenship is often, as was the case in the US and Britain, carried by the father, as Ann became a British subject by marrying Barack, if she did. Minor specified “citizen parents.” If you don't know the parents, particularly the father, you can't conform to Minor's definition, a definition which was last cited at least as late as 1939 in Perkins v. Elg, and certainly in 1916, by Breckenridge Long who pointed out Charles Evans Hughes' British parents in the Chicago Legal News. (thanks Sharon Rondeau).
Again, Barack never said he was a natural born citizen, and he told us again and again who his father was. There is no point, other than to tire out readers looking to understand, in fretting over Barack’s parent's citizenship status, bucause Barack told us he was born “A subject of the British Commonwealth.” If he lied, and doesn't know who his father is, he is a bastard, and cannot conform to Minor v. Happersett. If he knew who his father was, but lied, again and again, he may have been eligible, but will certainly not be re-electable, both for being a congenital liar, and perhaps because the father whose identity he presumably hid was hidden for a reason. If he told the truth, as we must assume, he doesn't conform anyway, and, in fact, told us he was naturalized, knowing that the fix was in, and that no legislator would defend the Constitution because it would bring down McCain, and end his or her career in government.
Since this thread is about the Order to Appear issued to Obama, I'll agree with those who see no way he will appear. His legal staff and the justice department have blocked discovery from the beginning, and they have - my favorite quote from former SEIU President, and regular at the White House, Andy Stern - “Use the power of persuasion, and if that doesn't work, the persuasion of power.” If votes get counted, which is a big question, Obama can be removed, but he is effectively a dictator. He will do whatever he wants to do. The Army didn't protect the Constitution and neither have the courts or legislature. That is why the House is presumably the most powerful force in the republic, to the extent that representatives reflect the wishes of those who voted them into office.
I see no provision of the 1948 BNA making Ann a UK subject by marrying BHO Sr.
Since the 1920’s under US law, Ann would not lose her US citizenship by marrying an alien.
