You are right on that one. If he was not born in the US I am not sure. McCain was born in Panama and both his parents were US Citizens. However, he was eligible to run for president. Still researching why he was eligible.
Have you read US vs Wong Kim Ark? Perhaps I am misinterpreting the decision, but I don’t think so. Having someone else read the decision would be helpful.
I have read dozens of cases, andcame to the conclusion that what I think doesn’t amount to a hill of beans its all up to SCOTUS and now that there are two more libs on it(whose jobs are at stake) it may reach a different decision than it would without them.
