Factoid: Section 301(c) of the Immigration and Nationality Act extends citizenship to anyone born to an American citizen — such as Cruz’s mother at the time of his own birth.
Fact: the Framers made a distinction between "citizen" for senators and representatives and "natural born citizen" for president. There is a difference.
It's really too bad that the brightest shining conservative star we have is not a natural born American citizen, but like Lakeshark said, he has not said anything about running for President at this time.
“Factoid” does not mean “a little fact.” It means something that looks like a fact, but isn’t. Just as an “android” looks like a man, but isn’t.
No one claims that Cruz was not born a citizen. The rigorists claim that the framers and ratifiers of the Constitution meant by “natural born Citizen” only a person born on U.S. soil of two citizen parents.
