You've been told many, many times over what the situation is with McCain and you still keep coming back to it as if it's a new subject when it isn't.
If you say you are going by Vattel and yet McCain isn't eligible according to you - then please provide the section of Vattel and the exact language that details why and under what circumstances McCain wouldn't be eligible.
What section of Vattel would render McCain ineligible?
Please answer the question rather than providing lame excuses for not answering the question.
