I never said there was.
Then why on earth should we accept it for Presidential eligibility? It is an unnatural creation of congress, not a characteristic of natural law.
The context of my comment was the "divided citizenship" of a husband having one citizenship, and a wife having a different citizenship. That is what you were talking about, and it's what I responded to.
I wasn't referring to dual citizenship of a single person, which was recognized by the US Supreme Court as far back as 1795, and which was held by Presidents Washington, Jefferson and Madison while serving as President.
Different concept.
And it is obviously a concept that frankly didn't bother the Founders and their generation that much, as long as the person holding it was loyal to the United States, because if they had, they would've raised a stink about it and forced Presidents Washington, Jefferson and Madison to renounce their French citizenship.
