Institute on the Constitution: Ted Cruz Can't Be President Because He is Not a Natural Born Citizen

Yesterday, the Institute on the Constitution reprinted an Orange County Register op-ed which declares Ted Cruz ineligible for the presidency because his father is Cuban. The article was posted by MD League of the South chaplain David Whitney.
Defining the “natural born citizen” clause of the Constitution in terms of parentage, the op-ed writer, Steve Jackson, comes to the the conclusion that Cruz’s father disqualifies the Texas Senator from eligibility.
Jackson writes that the founders got the term “natural born citizen” from a 1787 book by Emmerich de Vattel’s titled The Law of Nations – the Principles of Natural Law Applied to the Conduct and to the Affairs of Nations and of Sovereigns. He cites Book I, Chapter XIX, Section 212 which states: “…The natives, or natural-born citizens, are those born in the country, of parents who are citizens…”
Will Obama birthers come out in opposition to Cruz? Will those opposed to a Hispanic president use this as a means to trip up his chances? I don’t know whether the op-ed writer is accurate in his claims but it will be fascinating to see this play out.
