Cruz was BORN a U.S. citizen. He was not naturalized at any point in his life.
I did not write what you just quoted.
Yes, he was born a US citizen, but he does not appear to meet the standard of ‘natural born citizen’ as was used and applied at the writing of the Constitution.
I doubt it will be enforced, as Obama, at least by his public story of his origins, failed to meet it and is quite obviously holding office today—and I expect it’s just another bit of the Constitution that will be ignored.
My info is that Ted Cruz was born in Calgary, Alberta Canada and his father at the time was a Cuban citizen who fought for the Castro revolution but later turned against Castro and only his mother was a USA citizen. A very fascinating family history but as I see it, as a plain USA born citizen with/from non-naturalized parents at birth, Cruz is less eligible to be POTUSA than I am even though I served overseas in WWII.
