Trump, Clinton win 'corn kernel poll'

At the Iowa State Fair, Republican Donald Trump and Democrat Hillary Rodham Clinton appear to be their parties' leading presidential choices — for now. That's according to the unscientific "corn kernel poll."

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.

Meanwhile, New Jersey Gov. Chris Christie is criticizing former President Jimmy Carter's foreign policy record. Christie is the second Republican presidential hopeful to attack Carter's legacy within days after Carter announced that cancer that has spread to his brain.

On the Iowa State Fair's political soapbox, Christie also slammed President Barack Obama's foreign policy record and compared him to Carter, saying that Obama "makes Jimmy Carter look strong."

When asked later whether the remark was appropriate, Christie said he wasn't talking about Carter's health, but his presidency.

"We all wish the president the best, we wish for him to recover and to live a long and healthy life," Christie said. Adding that his comment was about Obama and less about Carter.
