More than 14 hours after the Iowa caucuses began, we still don’t have any official results, and it’s becoming clear that an app is at least partly to blame. An app designed to let caucus leaders report results seems to have had problems including user error, lack of connectivity and an insufficient backup plan, demonstrating exactly why it’s so difficult — and risky — to introduce new technology into elections. “Right now, a lot of the election security community is trying to, as nicely as possible, say ‘We told you so,’” said Maggie MacAlpine, a co-founder of Nordic Innovation Labs, a firm of security consultants whose specialties include safeguarding elections. This year, the Iowa Democratic Party, which runs the state’s Democratic caucuses, introduced a smartphone app that local precinct chairs could use to send in tallies from their caucus sites. Immediately, election security experts raised concerns because the party wouldn’t reveal who built the app, what testing had been done, or who they had consulted to make sure it was secure. The party insisted, however, that thorough security measures had been put in place, and besides, precinct chairs could always fall back on the reporting technology they’ve been using for decades: a phone-in hotline. One problem: Multiple precinct chairs reported hours-long wait times, and even getting cut off, when they tried to use that hotline.
