Nevada Dems canceled their caucus app. But that poses its own problems.

But in order to integrate the early votes effectively, the party will have to start training its volunteers now. Ruben Murillo Jr., a precinct chair in Nevada, said all the early training focused exclusively on the app, and no backup plan was ever detailed.

“They never did address what to do if the app wasn’t working, how you would incorporate those early votes,” Murillo said, adding that he plans to seek further training now that the app has been scrapped.

If the number of people who vote early is small, folding the early votes into the process on caucus day should be fairly easy for the volunteers in charge of the caucuses to handle, according to Barry Burden, the director of the Elections Research Center at the University of Wisconsin-Madison.

But he said the addition of paper ballots would almost certainly slow down the process — and if the people responsible for the caucus aren’t well trained, they could inadvertently reproduce the small but widespread errors that have already been documented in Iowa.
