Big crowds turned out Saturday for the Nevada Democratic caucuses -- leading to scattered delays and long lines throughout the state. 

Delays were still being reported, shortly before Fox News called the race for Hillary Clinton. 

The Nevada State Democratic Party told Fox News that many of the caucus sites remained open because of the heavy volume.

According to early entrance polls, there were a huge number of first time caucus-goers. Early entrance polls also showed minority voters turned out in strong numbers for the candidates, giving Clinton a very slight lead over Bernie Sanders from the beginning.

A large number of older voters were also showing up to the caucuses, according to early polling, with about 30 percent of attendees 65 or older.

Among those was Mary Moore, a 68-year-old retiree, who said she’d followed Clinton’s career for years.

"I've seen Hillary do things for the Mexicans, I've seen her do things for the blacks, the whites, all of them," said Moore, who is black, told The Associated Press. "It wasn't about just one color -- we're all God's children."

Moore, a former customer service representative for Delta Airlines, said she’s planning to speak up at the caucus.

"I'm going to be here to put her in office," she said. "They're going to hear my mouth. They're definitely going to hear me."

Clinton’s camp was counting on a strong turnout among Latino voters to hold off Sanders’ momentum in Nevada.

In the days leading up to Saturday’s caucuses, Clinton’s allies have worked to slam Sanders’ immigration record and criticized him as a johnny-come-lately to related issues.

Still, many Democrats like Andrea Reyes, a 29-year-old hair stylist, said Sanders would get her vote and expressed concern over some of Clinton’s donors.

"She's being funded by all the top dogs, we're being funded by the people," Reyes said at a Las Vegas Strip caucus site at Caesars Palace. "I don't want a politician who's going to stand up for corporations."
