Jon Ralston: “Donald Trump will be in Reno on Saturday, but the Republicans almost certainly lost Nevada on Friday.”

“Trump’s path was nearly impossible, as I have been telling you, before what happened in Clark County on Friday. But now he needs a Miracle in Vegas on Election Day — and a Buffalo Bills Super Bowl championship is more likely — to turn this around. The ripple effect down the ticket probably will cost the Republicans Harry Reid’s Senate seat, two GOP House seats and control of the Legislature.”

David Wasserman says Nevada may be “a potential top-to-bottom Republican disaster.”

Washington Post: “Katy Perry’s glamor, Tom Steyer’s money, Univision’s megaphone and organized labor’s muscle, along with a late assist from Barack Obama, each helped lubricate Harry Reid’s well-oiled political machine over the past 48 hours.”

“The media tends to focus on the lack of enthusiasm for Hillary Clinton relative to President Obama, which is real, but a few thousand more ballots were cast in Nevada on Saturday — during the first day of early voting — than during the kickoff day four years ago, when there was a similar flurry of activity to propel Democrats to the polls. And that was before Air Force One touched down yesterday afternoon.”

“It is a testament to the power of the organization that Reid, the retiring Senate Minority Leader, has built over three decades, which he is now using to get Clinton and his hand-picked successor, Catherine Cortez Masto, across the finish line. As much as 60 percent of the vote will be cast before Nov. 8 in the Silver State.”

A new Monmouth University poll in Nevada finds Hillary Clinton leading Donald Trump by just four points, 45% to 41%.

Key finding: 44% of Nevada voters believe that Clinton acted criminally in dealing with her private email server, another 27% say she showed poor judgment and just 13% say she did nothing out of the ordinary.

In the U.S. Senate race, Rep. Joe Heck (R) leads by two points over Catherine Cortez Masto, 42% to 40%.

Washington Post: “Saturday’s raucous state Democratic convention in Nevada encapsulated a lot of the themes of the party’s 2016 election in a relatively short period: complex delegate math, inscrutable processes, allegations of deceit, fury — and a result that doesn’t do much of anything to shift the race’s eventual outcome.”

Donald Trump was declared the winner of the Nevada caucuses on Tuesday night, the New York Times reports, “gaining a third consecutive victory in an early-voting state and strengthening his position in the Republican presidential race before the wave of Super Tuesday elections on March 1.”

“Mr. Trump was seen as a favorite going into the contest, and his victory serves as a setback for his chief competitors, Senators Ted Cruz of Texas and Marco Rubio of Florida, who must now try to break Mr. Trump’s winning streak in the larger states that vote in the coming weeks.”

The Nevada Republican Party has the results.

First Read: “Today is the Nevada contest on the Republican side, but don’t expect to find out the results at a reasonable hour. Caucus-goers start gathering between 8:00 pm ET and 10:00 pm ET (submitting votes via paper ballot). All meetings end by midnight ET. In addition, the contest doesn’t have a history of being well run.”

“Bottom line: We won’t know who wins until very late – even possibly tomorrow.”

Jon Ralston says the best case scenario is getting results by 2 a.m. ET.

“Donald Trump’s Republican rivals are seeking to make a stand against him in the Nevada caucuses on Tuesday, their last chance to slow his momentum before a dozen states vote on the party’s presidential nomination next week,” the New York Times reports.

“But it may be difficult to stop Mr. Trump in Nevada, where he has enjoyed a high profile because of his business dealings in Las Vegas and where only a small number of voters have typically participated in the caucuses.”

Politico: “Nevada is Donald Trump’s to lose. That, you can take to the bank. But variables that will crystallize the state of the race heading into next week’s Super Tuesday contests — the size of Trump’s expected win and the race for second place between Marco Rubio and Ted Cruz — remain wild cards here as Republicans head out to caucus on Tuesday.”

“Unlike in Iowa, where the state parties recruited Microsoft to build a high-tech caucus results reporting system, or New Hampshire and South Carolina, where state elections officials conduct the primaries, in Nevada county GOP officials have responsibility for holding local caucuses, counting ballots and reporting results,” the Wall Street Journal reports.

“Republican volunteers at each of the 36 caucus locations will count ballots by hand, write the results on an envelope, take a photograph of the envelope and text the photo to Ed Williams, the Clark County Republican Party chairman, and to state GOP officials. The state party is also allowing the Associated Press to monitor the results as they come in from precincts; in 2012 the party announced results itself on Twitter.”

Bernie Sanders acknowledged that he “failed to turn out as many people in the Nevada caucuses as he hoped he would, a factor the Vermont senator suggested contributed to his loss on Saturday to Hillary Clinton,” the Washington Post reports.

Said Sanders: “What I’ve said over and over again, we will do well when young people, when working-class people come out. We do not do well when the voter turnout is not large. We did not do as good a job as I had wanted to bring out a large turnout.”

Clare Malone: “For starters, when it comes to surveying public opinion, Nevada is still very much the Wild West, and pollsters may be unwilling to gamble their reputations on the state: Nevada is among the hardest places to poll in the nation, with a spotty track record to prove it.”

“Nevada populace’s is still pretty unfamiliar with caucusing, making for difficult polling work.”

“Nevadans are also notoriously hard to pin down for a survey. Many work night shifts, thanks to the state’s thriving hotel and gaming industry, meaning that they aren’t home to answer the phone in the evening, when polling calls are typically placed… And given that the state’s population is highly transitory — the bright lights and job prospects on the Strip draw people in like moths to a flame — phone calling can itself be a highly inefficient process.”

A new Gravis Marketing survey in Nevada shows Hillary Clinton leading Bernie Sanders among likely caucusgoers, 53% to 47%.

On the Republican side, Donald Trump leads with 39%, followed by Ted Cruz at 23%, Marco Rubio at 19%, John Kasich at 9%, Jeb Bush at 5% and Ben Carson at 5%.
