Early reports from the Nevada caucus indicate that the locations are "very crowded" and somewhat disorganized, with basic caucus procedures being ignored.

At Bonanza High School in Las Vegas, the scene was described as "s--t show" and caucus volunteers were breaking protocol and openly supporting a candidate.

Says caucus volunteers are wearing Trump gear (they're not allowed to show preference). "Actively bullying folks. Not checking IDs." — Elaina Plott (@elainaplott) February 24, 2016

More from Rubio source: "They didn't ID one of our staff. We alerted the site manager." This is at Bonanza High School. — Elaina Plott (@elainaplott) February 24, 2016

Updated quote from source: "40-50 loose ballots on table." Counter looked at them, put them under envelopes. Wouldn't budge when called out. — Elaina Plott (@elainaplott) February 24, 2016

Elsewhere, IDs were not being checked and ballots were handed out "willy-nilly."

Man here says "it's a disaster." No one is checking in or checking IDs. They're handing out ballots willy nilly. Some guy voted trump twice — Emily Cahn (@CahnEmily) February 24, 2016

Second woman says no one checked her ID. She was just handed a ballot. She says it's very scary. #Nevadacaucus pic.twitter.com/VqxrOianFj — Emily Cahn (@CahnEmily) February 24, 2016

Now an announcement that they ran out of ballots. They "weren't expecting a crowd this size." #Nevadacaucus — Emily Cahn (@CahnEmily) February 24, 2016

Other places reported running out of ballots as well:
