riddle me this

The Constitution provides that “No person except a natural born Citizen . . . shall be eligible to the Office of President.”  Ted Cruz, being born in Calgary, CANADA and lived there for his first four years…is technically not a natural-born citizen, right? Cruz claims the law has been clear that US Citizens born abroad are natural-born…but the courts actually haven’t said that.  Cruz has even go so far as renouncing his Canadian citizenship in ’14? (as did his father in ’05).  I’m sure Canada isn’t shedding any tears over it.
