The universe is full of silly notions, but the courts have already made clear that they don’t care about this issue. Judges, especially the liberal ones, don’t think this clause applies anymore. Even strict original intent crowd believe that this clause is present in order to prevent a subject of the King of England becoming President. This issue is moot.
Why would they want to prevent a subject of the King of England from becoming President? For exactly the same reason that we would not want a President influenced by foreign powers at this time. The question is far from moot!
