Agreed. They have had a string of recent successes in doing so.
Legislative intent is a foundation issue in understanding and properly applying the law.
Again, agreed. Few are better at it that Justices Scalia and Thomas.
You missed my entire point, which was that arguing original intent on this issue will get us back in front of SCOTUS where we will lose because they are not going to overturn decades and decades of case law (over and above citizenship cases) that rests on the phrase "subject to the jurisdiction." We will ultimately have to get a constitutional amendment to end birthright citizenship. If I am wrong, hallelujah!
Well, you’re right, but SCOTUS is not the end of the line as so many think.
When SCOTUS blatantly ignores or rewrites the Constitution in its decision, that decision (or the part of the decision that is contra the Constitution) is invalid and not constitutionally binding. Using the Constitution as the basis and giving notice as to why it is unconstitutional, either another federal branch or a state may call out the decision as unconstitutional and, therefore, invalid, null, and void.
