For natural born citizen there was at the time the Constitution was written, and absent any amendment, there still is.
There is an exception for those born of citizen parents in the armies of the nation. So McCain qualifies under that.
Unless you start making up your own version of the United States Code, you cannot find a statutory requirement for both parents of a President to be US citizens nor is there a requirement that his birth occur on US soil.
We're not talking about citizen at birth, but rather Natural Born Citizen, which remains what it was in the late 1780s when the Constitution was written and ratified. No meer law, which is what the US code is, can modify the meaning of a Constitution term.
Again, natural born citizen is not the same as citizen at birth. Those people born outside the US who are citizens at birth strictly due to the statutes are, under various Supreme Court rulings, "naturalized at birth".
For your information I have nieces, a nephew and great nieces who are "persons of color". One niece and nephew have a Black father, the other niece has a Hispanic father. The great nieces are her daughters, one of whom is much more Hispanic looking that the other. They are under the legal custody of my wife and I. We love them, even if the older one drives us up the wall (she's a pre-teen, it goes with the age and the hormones kicking in.) We also love the two "half black" ones. Their father is a good man, especially in comparison to the white husband their mother had before him, who was a slime ball scum bag. But even in an absolute sense, he's a good man. The definition of Natural Born Citizen, comes not from the law, but from the well understood meaning of the term under Natural Law, which has nothing to do with race or ethnicity. It has to do with citizenship of the parents, however they obtained that citizenship, and in general also with place of birth. It's most likely your man wasn't even born in the US, but that's not proven, legally, one way or the other, although it would certainly be easy for him to do so, rather than arguing "standing" and "justicibility". If that is the case, his father's citizenship status would not matter. But if he was born, as alleged, in Hawaii, he's still not eligible because of that citizenship status (alien) of his father. You imply in your blog that his father was an immigrant, but he was not, he was visiting student. That would not be true of my half black or half Hispanic relatives. All of them were born in the US of two citizen parents, and when they reach 35 they will be eligible to the office of President. Couple of 'em might even make a run at it. In particular my niece, who has a 4.0 college GPA, about 3/4 of the way through a 4 year nursing program. I demand that you post an apology to your blog for even implying that I'm a racist.
