“We will probably never really know whether an American citizen born outside the US can become President (or Vice-President) until a lawsuit involving such a candidate finds its way into the courts. This could happen, of course, if a foreign-born candidate were elected and the electoral college’s choice were challenged in court; or, more likely, if such a candidate’s right to federal campaign subsidies (matching funds) were questioned, or if a challenge were mounted against a foreign-born candidate’s right to be included on a state primary election ballot.”
Seems to me it could be settled a lot less dramatically by simply having the Congress address the issue specifically the matter of dependents born while the parent was assigned to an overseas post as an agent or employee of the U.S. government.
