Donald Trump speaks during the family leadership summit in Ames, Iowa Saturday Aug. 10, 2013. Republican presidential hopefuls are hoping to impress conservative voters at the conference organized by an influential Christian group. The daylong event will be one of many candidate cattle calls in the grueling run-up to the 2016 presidential election. None of the potential contenders appearing Saturday has declared candidacy. Conservative voters could be key to a 2016 victory in Iowa's caucuses, the nation's first presidential nominating event. (AP Photo/Justin Hayworth)
