As for dual citizenship, 3 of our first 4 Presidents were dual citizens, while serving as President. Nobody cared.
As for the other:
"It is not necessary that a man should be born in this country, to be 'a natural born citizen.' It is only requisite that he should be a citizen by birth, and that is the case with all the children of citizens who have ever resided in this country, though born in a foreign country."
- James Bayard, A Brief Exposition of the Constitution of the United States (1833)
The above quote was part of Bayard's discussion of qualifications to be President and Presidential eligibility.
Bayard's exposition of the Constitution was read and approved by the Great Chief Justice of the Supreme Court John Marshall, by the legendary Supreme Court Justice Joseph Story, and by the famous Chancellor James Kent, as well as other legal experts of the early United States.
Not one single person ever said he was wrong about his understanding of what "natural born citizen" meant.
Because it was a secondary citizenship acquired for the purpose of commerce and had no affect on the primary American citizenship:
There is, however, some relaxation of the old and stern rule of the common law, required and admitted under the liberal influence of commerce. Though a natural born subject cannot throw off his allegiance, and is always amenable for criminal acts against his native country, yet for commercial purposes he may acquire the rights of a citizen of another country, and the place of domicil determines the character of a party as to trade.

Really Jeff? Again with posting quotes with no sources?
A Brief Exposition of the Constitution of the United States
Is it because you don't want people to read down to page 4 and see this was not a book of law but an instruction book for 'youth'?
Or to see that when you say the legal authorities 'approved' the work, (insinuating they agreed with everything Baynard said) they actually, did nothing more than to give their appoval of the project itself and it's purpose?

Why don't you source it, Jeff?

Jeff, what you posted would work for John McCaine. He is a citizen by birth, born outside the country to citizens, plural, mother and father which is what this says is required to be a natural born citizen.
Obama and Cruz both fail. Both only have one citizen parent. BVB
