“The Constitution is quite clear that no person “except a natural born citizen” is eligible to be president of the United States, but there is no such restriction placed on a president’s wife. Louisa Adams is the only one of a long line of First Ladies who were born abroad, and although her father was an American and citizenship her birthright, it became an issue that was used against her husband, John Quincy Adams, when he ran for the presidency. It was a whispering campaign, to be sure, because most people knew very well that Louisa was as much a citizen as they were. A large number of people didn’t understand that children born to Americans abroad inherited their parents’ rights, and in Louisa’s case, even some of those who did know this weren’t so sure that the rule applied to her because her mother was a British subject.”
