The Constitution only says "natural-born." It is up to the Congress to determine what that constitutes natural-born within any reasonable interpretation of the phrase, and we have the courts (supposedly) to keep Congress from going too astray in its determination. Given that this was the first Congress, which was full of our revolutionaries and which wrote the Bill of Rights, I tend to believe the interpretation of 1970 was what was meant.
And I agree with you. As far as I'm concerned McCain meets the full Constitutional requirements for the job.
But you and I don't get to make that call.
IF it comes to serious question, the Supremes get to make the call.
Definitely not the law brother. To the contrary, Congress has no power to determine what constitutes Natural Born under the Constitution, other than to propose Amendments to the Constitution to the several states for consideration and adoption.
