Ted Cruz?
Senator Ted Cruz who was born in Canada to a Cuban citizen father is definitely not constitutionally eligible to be President and Commander in Chief, or VP. Ted Cruz is not a “natural born Citizen” of the United States. His basic citizenship would have been obtained only under U.S. statutory naturalization laws enacted by Congress, not Natural Law. The adjective “natural” means something very specific in legal terms. Look up the term “natural” in a legal dictionary. It is something not created my man, i.e., in the case of citizenship it would be a Citizen not created by any man-made law, treaty, or act. Others other than Ted Cruz who are frequently mentioned for high national office are also not eligible.
