The Cruz birthers

Legal scholars are firm about Cruz’s eligibility. “Of course he’s eligible,” Harvard law professor Alan Dershowitz tells National Review Online. “He’s a natural-born, not a naturalized, citizen.” Eugene Volokh, a professor at the UCLA School of Law and longtime friend of Cruz, agrees, saying the senator was “a citizen at birth, and thus a natural-born citizen — as opposed to a naturalized citizen, which I understand to mean someone who becomes a citizen after birth.”

Federal law extends citizenship beyond those granted it by the 14th Amendment: It confers the privilege on all those born outside of the United States whose parents are both citizens, provided one of them has been “physically present” in the United States for any period of time, as well as all those born outside of the United States to at least one citizen parent who, after the age of 14, has resided in the United States for at least five years. Cruz’s mother, who was born and raised in Delaware, meets the latter requirement, so Cruz himself is undoubtedly an American citizen. No court has ruled what makes a “natural-born citizen,” but there appears to be a consensus that the term refers to those who gain American citizenship by birth rather than by naturalization — again, including Texas’s junior senator.
