You lost this one.
Furthermore, McCain took up this issue, on his own, in Congress, and not a single member challenged McCain's Citizenship status.
You can find not one single law or court ruling, anywhere, which applied at the time of McCain's birth, that would indicate that McCain is NOT a Natural Born Citizen.
Folks, try to separate the law from your personal feelings about individuals.
Don't let personalities bias things. We should be trying to craft law that will survive all of us.
