•Rafael Edward "Ted" Cruz
â—¦Born December 22, 1970, in Calgary, Alberta, Canada, of a father who was a citizen of Cuba, and a mother who was a citizen of the U.S.
â—¦Sen. Cruz is not eligible to be president, and could only be made eligible in two ways. One would be for at least the small parcel of land in Calgary on which he was born to be ceded to the U.S. and made incorporated territory for the duration of a term as president. It could not just be U.S. soil at the moment he might be inaugurated, but it could remain Canadian soil until that moment, and then be ceded back when his successor is inaugurated. The second would be for the province of Alberta to secede from Canada and be admitted as a state of the U.S. before the term of presidency would begin. The spot doesn't have to be U.S. soil as of the date of birth, only for the duration of the term in office.
