> And that legislation needs to specify a meaning for Natural Born. <
Agreed. There is too much ambiguity in the phrase now. And it should be done as a constitutional amendment. (I know...according to the Federalist Papers, etc., etc. But none of that carries the force of law.)
The amendment can be just this simple: Natural Born shall mean born within the United States, of parents both of whom were born within the United States.
As an aside, I don’t think such a proposal would ever be accepted. It would be smeared as racist, or elitist, or some such thing.
You might be right.
But they might be able to say in the legislation that the meaning shall comply with the 758 Law of Nations, without directly stating the meaning.
And the likelihood that Congress will fail to enact such legislation is exactly why we need the states pushing for it. It would only take one or two states that were successful in enacting that legislation to throw a huge spotlight on it. A candidate not making the ballot because he is inelligible would be national news. There would be court challenges, etc.
All one has to do is examine how Congress handled the Obama birth controversy to see that they just don't care about this issue. The most you would ever get is that the candidate himself must be born in the U.S. However I am not sure that would pass.
