JIM YOUNG/REUTERS Donald Trump has extended his winning streak to three after Tuesday's victory in Nevada.

Donald Trump won the Nevada GOP caucuses Tuesday in a messy night of voting punctuated by allegations of fraud, intimidation and a slew of other instances of disorganization and chaos.

In one of the most extreme cases of such irregularities, several alleged Trump supporters at a caucus site at a Las Vegas high school were photographed sporting white, hooded Ku Klux Klan robes.

The men, holding signs saying they were members of the New England Police Benevolent Police Association — a controversial group that endorsed Trump in December — expressed their support for the GOP front-runner. “Make America Great Again,” one sign said.

It remained unclear — even to people who purportedly witnessed their presence — whether the men were actual Trump backers or were merely drawing attention to the bigoted rhetoric the bombastic billionaire has employed on the stump.

The robed men, however, were just one of a myriad of problems that plagued multiple caucus sites, filling the voting process with nearly as much pandemonium as the mogul’s campaign itself.

Despite the disorder, Trump sailed to an easy victory, extending his current winning streak to three — the magnate won the New Hampshire and South Carolina primaries — and charging his already surging campaign with momentum heading into “Super Tuesday” on March 1, when GOP voters in 12 states and American Samoa will head to the polls.

The Associated Press, as well as multiple television networks, projected Trump the winner as soon as caucus sites closed Tuesday evening.

With 10% of precincts reporting, Trump had the support of 45% of caucusers, compared with 24% for Marco Rubio and 21% for Ted Cruz.

Ben Carson came in a distant fourth with 6% support.

Trump acknowledged his landslide win in a triumphant speech.

"A couple of months ago we weren't expected to win this,” he said as an excited crowd chanted his last name. “Now we're winning, winning, winning the country … .and soon the country is going to start winning, winning, winning.”

“We won with everyone tonight,” Trump said of his success with various demographics. “We won big with the poorly educated. I love the poorly educated.”

Several Nevada caucus-goers took to social media throughout the evening to complain that people had voted multiple times, that site supervisors failed to check IDs and were wearing Trump apparel, and that multiple sites ran out of ballots.

“Man here says ‘it's a disaster,’” one reporter present for the havoc tweeted. No one is checking in or checking IDs. They're handing out ballots willy nilly. Some guy voted Trump twice.”

Other caucusers complained on social media of other widespread disorganization, including several instances of ballots that included the names of several candidates who have already dropped out of the race.

Likely exacerbating the problems Tuesday night was high voter turnout.

An official with the Nevada GOP said that 37,000 Republican voters had pre-registered by 2:00 p.m. local time, hours before the caucuses even began — a total that surpassed overall turnout in the state’s 2012 contest.

But the confusion Tuesday is nothing new for the state.

Many of Nevada's past caucuses have been plagued by disorganization. In the 2012 GOP contest, only 33,000 Republicans caucused, but it still took state party officials nearly three days to tally and release results.

The Democratic Party's caucuses in the state on Saturday were also messy, with universal reports of long lines to get into — and no accommodations for disabled voters at — caucus sites, and allegations of many improperly tallied votes.
