Senator Ted Cruz has a birth certificate which shows that he was born in Canada, of an American mother, an a Cuban father, but has never been challenged, by Donald Trump, as to his qualifications to run for the Presidency of the United States of America.
President Obama, has an Hawaiian birth certificate which shows that he was born in one of the States of the Union, of an American mother. Even if he had been born in Kenya, he like Cruz, and John McCain, who was born in Panama, Obama would still have been an American citizen.
Donald Trump, Birther-in-Chief, by implying that Obama is not a legitimate U. S. citizen, is not impugning Obama but rather his mother, a daughter of a World War II U.S. Army veteran. At the same time, Trump's own mother was born in Scotland and, to my knowledge, he has never produced her naturalization papers to indicate that she was a U.S. citizen at the time of Donald's birth. Perhaps Donald, too, is an anchor baby.
