Despite the absence of an official straw poll, the 2015 Iowa State Fair held an informal poll of its attendees (both Republican and Democrat), and found Donald Trump to be the most favored GOP candidate, and Bernie Sanders the most popular Democrat. Ted Cruz went on to win the Iowa GOP caucuses, defeating Donald Trump by 4 percent, while Hillary Clinton defeated Bernie Sanders by less than 1 percent on the Democratic side.
