Birthers will soon have a chance to lose on that issue, like they always lose.
Make your argument.
You sound like a good many friends of mine who, being liberal, like to spout off declarative statements of absolutes but, can never really make their case.
If Cruz were to be called by the draft and he wanted to avoid it all he would do is walk across the border and into Kannaduh.
The USA would not be able to sole jurisdiction, by way of citizenry and Kannaduh would say “Hey, he’s our guy two. Don’t mind helping you most of the time but, as a citizen of Kannaduh he is welcome for as long as he likes”.
The fact that he was not born in the USA, of one American Parent and never renounced his citizenship, qualifies him as dual citizen, with divided obligations and loyalties, which he exercise anytime.
One is wholly one thing or another or two parts of other things.
