When it counted the electoral votes without raising the issue as a challenge, Congress decided that a dual citizen can also be a natural born citizen. No Court is going to touch the question. I doubt a majority of the public cares one way or the other.
I think you have hit the nail on the head. Since the Constitution provides no specific mechanism for determining whether a candidate meets Constitutional requirement, it by default is left up to the voters, the Electoral College and Congress.
Each has the duty to determine if a candidate is qualified. If no objections are raised by these bodies, I’m not sure I want a court stepping in and overriding them.
If we’re all so concerned about this issue, why isn’t anyone, to my knowledge, working for a policy that would prevent a future situation of this type?
All it would take is one state requiring all candidates present appropriate documentation before going on the ballot.
