He must have been a two-term usurper!!
"Birth certificates were not common in this country until the first decade of the 20th century, so most of our presidents would not have had birth certificates. I cannot find the reference at this moment, but at least one of Ike's biographies I have read was explicit that he did not have a birth certificate. Neither did Harry Truman, although the folks from his home town issued him one after he became President to make up for that shortfall. Ronald Reagan is perhaps the most recent President born without a BC, as Illinois was late to come on board with requiring birth certificates until after his 1911 birth."
