"Yes, he is a natural born citizen." -- The Supreme Court cases that I've seen referenced that seem to address this rather ill-defined term looked to me to come down on defining "natural born citizen" as "citizen *BOTH* of whose parents were citizens at the time of his birth". That's why we couldn't back Rubio for President - his folks weren't naturalized until after he was born. In Obama's case, unless DNA testing could show that Barry, Sr., *wasn't* his father, then while he *is* a US Citizen by the 14th Amendment, he is NOT a "natural born" citizen. Thus, he would appear to be ineligible to hold the office.
