I hate to break it to you... Cruz was born in Canada.
A seemingly parallel case that involved an Italian chap named Bellei showed that if a man’s citizenship status was granted by an act of Congress effective as of his birth, it could be un-granted by another act of Congress. They can’t name names, to be true, but they can specify classes of people.
Now if I read things right, Cruz did have the additional circumstance of being born on a US Air Force base in Canada. That might change how a court reads it. Maybe a military installation would have some pull in the matter, so to speak.
It’s currently up in the air because we have no authority in the sky as to NBC. It really is a matter of what Caesar’s courts do.
To an American mother. So there, suck on that for awhile.
