As I said, the actual Constitution does not have specifically numbered clauses. Some reproductions of the text insert clause numbers; some do not. The more discerning reproductions place the original Article 2, Section 1 paragraph considered to be clause 3 in italics or a different color while noting that is has been superseded by amendment. The Senate version to which you link does that.
So for the purposes of inserting clause numbers into the text, the original Article 2, Section 1 paragraph that would have been called Clause 5 is now technically Clause 4. It’s somewhat silly and a point of interest to legal geeks only, but there it is.
And....since WKA was found to be a "citizen", what that really means is that since it involves Barry O it was really supposed to mean WKA was a NBC and therefore Barry is one too.
Yup. You betcha toc!
