Article I of the Constitution grants Congress the power to naturalize an alien — that is, Congress may remove an alien’s legal disabilities, such as not being allowed to vote. But Article II of the Constitution expressly adopts the legal status of the natural-born citizen and requires that a president possess that status. However we feel about allowing naturalized immigrants to reach for the stars, the Constitution must be amended before one of them can attain the office of president. Congress simply does not have the power to convert someone born outside the United States into a natural-born citizen.
Let me be clear: I am not a so-called birther. I am a legal historian. President Obama is without question eligible for the office he serves. The distinction between the president and Cruz is simple: The president was born within the United States, and the senator was born outside of it. That is a distinction with a difference.
It is pretty obvious what the framers intended. "Natural born" means born in this country.
Cruz needs to remain in the Senate and continue to piss off his colleagues in both parties.
