Iowa's Democratic Party turned to an untested software platform tied to a mobile application to streamline reporting from its presidential caucuses last night. What could possibly go wrong?

In a collapse that echoed the failure of a canvassing application used by Sen. Mitt Romney's 2012 presidential bid, the caucus reporting app repeatedly hung as precinct leaders attempted to submit returns. A backup hotline was jammed for hours. And as of the morning after the caucuses, the full results are still not tallied.
