Iowa State Fair

Promotions producer Kevin Rivers says the poll has been hosted by WHO-TV at the fair for at least a decade, according. Fair goers drop kernels into jars marked with the candidates faces. Fairgoers aged 18 and up can vote once a day for free.

By midday Saturday — the final day of the fair — nearly 50,000 votes had been cast. On the GOP side, businessman Trump led with 12,022 votes. With Democrats, former Secretary of State Clinton led with 8,757 votes.

That's as close as Clinton and Trump's massive entourages came at the state fair, a rite of passage for any presidential candidate. 

The respective Democratic and Republican front-runners each drew large crowds of gawkers as Clinton sampled a pork chop on a stick and Trump gave rides to children on his helicopter emblazoned with his famous last name.

Clinton tells reporters at the Iowa State Fair on Saturday she was going to let the inquiry into her email use go forward. Clinton turned the server over to the FBI recently to investigate the security of her email setup.

Thousands of pages of her emails publicly released in recent months show Clinton did receive messages later marked classified, including some that contained material regarding the production and dissemination of U.S. intelligence.
