Gov. George Romney and his son, Mitt, look out over the New York World's Fair grounds May 18,1964 from the heliport after attending a Michigan breakfast at the Top of the Fair Restaurant. The governor and a large delegation from Michigan are here for Michigan Day at the fair. At right is part of the Chrysler exhibit and behind them is the Ford exhibit. When George Romney ran for the 1968 Republican presidential nomination, his Mormon heritage was merely a footnote. It was scarcely mentioned in news accounts of the day. But for son Mitt Romney, the family religion presents a formidable political hurdle. (AP Photo).
