Presidential candidates of every stripe were at the fair this weekend, mingling with voters in the first-in-the-nation caucus state, taking questions on the Des Moines Register Soapbox and, of course, chowing down on some deep-fried food. Photographer Landon Nordeman traversed the fair in search of presidential candidates and interesting people. These are his photographs from the first three days of the event.

Trump poses with supporters' children before taking some of them on a free helicopter ride. He arrived at the fair shortly after 1 p.m. in grand fashion, landing in his private helicopter with "TRUMP" emblazoned on its side. The fair wouldn't let Trump's helicopter take off from the fairgrounds, so he used a nearby parking lot to make the flights.

After a short chat with the media, Trump enters the fairgrounds, where he was mobbed by hundreds of fairgoers who wanted to shake his hand or just snap a photo of him. He was closely guarded by a half-dozen security guards and another 10 police officers, a mix of local cops and state troopers.

Democratic presidential candidate Hillary Clinton meets the press. She was introduced by former Iowa Sen. Tom Harkin, who endorsed Clinton earlier this week. She was immediately asked about the swirling controversy over her use of a private email server while she headed the State Department. Friday night, Clinton joked about why she loves the social media app Snapchat, saying, "those messages disappear all by themselves."

Republican presidential candidate Jeb Bush speaks to journalists on Friday, August 14. The former Florida governor got grief over the Iraq War launched by his brother. One of the fair-goers asked Bush whether he was being advised by Paul Wolfowitz, George W. Bush's deputy secretary of defense and the architect of his Iraq War policy. Bush said Wolfowitz was providing some advice, but he insisted he was his "own person" and pointed the audience to the foreign policy speech he gave earlier this week in California, saying that was where he articulated his policies if spectators wanted more information.

"I believe we can get it to 6 or higher with a fair tax. I'm convinced," Huckabee told a crowd of potential caucus-goers at the Iowa State Fair on Thursday. "I guarantee you we will goose the economy if you bring $11 trillion of working capital back to this country."
