Much like Judge Morrow.
“Counsel for the United States have argued with considerable force against the common-law rule and its recognition, as being illogical, and likely to lead to perplexing, and perhaps serious, international conflicts, if followed in all cases. But these observations are, obviously, addressed to the policy of the rule, and not to its interpretation. The doctrine of the law of nations, that the child follows the nationality of the parents, and that citizenship does not depend upon mere accidental place of birth, is undoubtedly more logical, reasonable, and satisfactory, but this consideration will not justify this court in declaring it to be the law against controlling judicial authority. It may be that the executive departments of the government are at liberty to follow this international rule in dealing with questions of citizenship which arise between this and other countries, but that fact does not establish the law for the courts in dealing with persons within our own territory.” Judge Morrow, North District of California, Wong Kim Ark
Again, The U.S. v. Wong Kim Ark ruling required non-citizen parents to be permanently domiciled in the U.S. Obama's father was only in the U.S. on a temporary student visa and was never permanently domiciled in the U.S. The U.S. v. Wong Kim Ark ruling doesn't apply in Obama's case.
"The evident intention, and the necessary effect, of the submission of this case to the decision of the court upon the facts agreed by the parties were to present for determination the single question stated at the beginning of this opinion, namely, whether a child born in the United States, of parent of Chinese descent, who, at the time of his birth, are subjects of the Emperor of China, but have a permanent domicil and residence in the United States, and are there carrying on business, and are not employed in any diplomatic or official capacity under the Emperor of China, becomes at the time of his birth a citizen of the United States. For the reasons above stated, this court is of opinion that the question must be answered in the affirmative."
Yes, he might.
I would like to have a look though at Morse’s other statements, and try and figure out whether he’s actually contradicting himself or not.
He certainly has clearly stated, in the passage you cited, that the children born on US soil of alien parents are US citizens.
