In interviews, three caucus volunteers described serious concerns about rushed preparations for the Feb. 22 election, including insufficient training for a newly-adopted electronic vote-tally system and confusing instructions on how to administer the caucuses. There are also unanswered questions about the security of Internet connections at some 2,000 precinct sites that will transmit results to a central “war room” set up by the Nevada Democratic Party.

Some volunteers who will help run caucuses at precinct locations said they have not been trained on iPads that the party purchased to enter and transmit vote counts. Party officials scrambled to streamline their vote reporting system — settling on Google forms accessible through a saved link on the iPads — after scrapping a pair of apps they’d been planning to use until a similar app caused the fiasco in Iowa two weeks ago.

The volunteers also said the party has not provided sufficient training on how to use the Google form that will compile vote totals, a complicated process in a caucus.
