With the Nevada Democratic caucuses only a week away, both caucus workers and presidential campaigns are worried about the lack of detail the state party is providing about how the results reporting process will work.

The worries come after the state party stopped working with Shadow Inc., the company behind the app whose “coding errors” were at the heart of the chaos of the Iowa caucuses.Having scrapped plans to use a pair of Shadow’s apps, the parties will instead use a “caucus calculator,” as outlined in a new memo released by the Nevada State Democratic Party Thursday.

Described as “user friendly,” the calculator will be used to add early voting data into each precinct and calculate totals on caucus day, February 22, along with paper work sheets. The tool, which the party does not consider an app, will be available on iPads owned by the party and “accessed through a secure Google web form.”
