This is not an issue of whether or not the U.S. Constitution matters. Of course the U.S. Constitution matters. This is an issue of what the U.S. Constitution requires. Just because I disagree with you about what the term “natural born citizen” means does not mean that I don’t think the Constitution matters, and it certainly does not mean I am not a conservative.
Reasonable conservative minds can disagree.
You may disagree but a great many Constitutional scholars will tell you that you’re wrong.
