A little after four hours after the caucuses began, volunteers received a text from the state party with three new phone numbers to call to report results. Caucus precinct chairs found these numbers had operators who answered the phones and could take their results.

After Iowa’s caucus reporting system crashed with about 80 phone operators in Des Moines earlier this month, Nevada had 200 operators on site at the Rio Convention Center in Las Vegas. When reports came in about phone lines being jammed, the party texted its volunteers with the three new phone numbers — a move precinct leaders said made it far easier to reach an operator to report results.

“They did gave three different numbers and said if we couldn’t get through they would call us back,” said Ruben Murillo, a precinct chair at Coronado High School in Henderson.

Phil Sobutka, who spent more than 30 minutes dialing and redialing the party’s results hotline after his Henderson caucus finished, said the new number worked the first time he tried it.

Still, the process of reporting caucus results under the current D.N.C. rules is a long one.

Nevada’s caucus had 12 names on its ballot — 11 candidates and uncommitted. (Several candidates who have dropped out of the race remained on the ballot.)

For each candidate, Nevada precinct leaders had to report six sets of results — early votes, in-person votes and total votes for both the first alignment and second alignment. Then the precinct leaders had to report delegate totals for each viable candidate, as well the viability threshold for the precinct.

The phone operator would confirm each number with the precinct volunteer. And then once the data had been collected by phone, it would be checked against a photograph of worksheet the precinct volunteers were instructed to text to party headquarters.
