Democratic presidential hopefuls were left waiting at the Iowa caucuses on Monday night, amid problems tallying the votes.
The Iowa Democratic Party struggled with a new voting app it had launched for Caucus Day, which when combined with the complexity of the caucus process caused significant delays in vote reporting.
As a result, party officials had to rely on photos of the results and the counting of paper votes to ensure it matched earlier electronic reporting, a process that took much longer.
The IDP said that the problems with the electronic results were not the result of hacking.
"The integrity of the results is paramount," said IDP spokesperson Mandy McClure. "We have experienced a delay in the results due to quality checks and the fact that the IDP is reporting out three data sets for the first time."
Among those waiting to find out how they had performed was Minnesota senator Amy Klobuchar, who took advantage of the delay to be the first candidate to give a speech to their supporters, gaining some valuable national TV exposure in the process.
Early indications suggest that the fight for Iowa's 41 delegates is between Bernie Sanders, Elizabeth Warren, Pete Buttigieg and Joe Biden, though Klobuchar is hoping to leapfrog Biden into the top four.
"We know one thing: We are punching above our weight. ... Somehow, some way I'm going to get on a plane tonight to New Hampshire," Klobuchar said.
"We have beaten the odds every step of the way. We have done it on the merits, we have done it with ideas, and we have done it with hard work."
