If so, then what do we do about President Chester A. Arthur? He would be the first British subject to be president, beating out Obama by a century. Arthur's father was an Irish preacher (a British subject) when Chester was born. The father became a naturalized citizen later in life, when Chester was about 13 years old.
*Are you saying that Obama was born in Britain, or just that his father was a British subject? "British subject" and "British-born subject" are two different things.
If the Supreme court rules in favor of Obama, we then have precedent for every anchor baby ever born here. Kings and queens will have their children born here, educated here, and then run them for president. In effect, they will amend the constitution by judicial fiat, subverting Washingtons intent on keeping foreign influence from the administration of our government.
This Barn door has to be closed by the citizens in 2012 with an overwhelming vote against Obama.
