McCain was born in Panama on a naval base.
That makes it sovereign US territory.
Had he been born in Timbuktu It still would not be an issue.
It did however muddy the waters on the debate of baracks citizenship.
In my mind, the fact that Obama’s mother was a US citizen gave him the right to be a US Citizen.
Conversely The fact that his father was a British subject gave him the right to being a British citizen.
I believe that he had to make a legal choice upon the event of becoming a legal adult.
We don’t know what that choice was as Obama has kept his past shrouded in mystery.
Many surmise that this is being done simply to keep conspiracy accusations from the right alive so that they can be mocked as kooks.
