Concerns are growing that next week’s Nevada caucuses could offer a repeat of the chaos that ensnared the Iowa vote. Nevada is facing many of the same organizational and technical challenges that crippled Iowa’s process. Volunteers who will be leading the Feb. 22 caucuses say key information has yet to be shared. There has been no hands-on training with iPads being deployed to caucus sites on Election Day nor opportunities to try out a new “tool” that will be loaded onto the iPads and used during the caucus process. Nevada Democrats were initially working with the same app developer used in Iowa but scrapped those plans after the company’s app failed there.
