Hillary Clinton’s campaign manager briefed some of her most loyal and active fund-raisers this morning about the upcoming Nevada caucuses and responded to frustrations among some of her donors that the campaign needed to do a better job of demonstrating its successful mobilization of grassroots activists and small donors.

Robby Mook, the Clinton campaign manager, sat at the head of a conference table in the New York office of Clinton donor and Wall Street investor Marc Lasry, according to accounts from people in the room. Joining them for the state-of-the-race conversation over coffee were members of the campaign’s finance steering committee, including Maureen White, the former Democratic National Committee finance chairwoman, Alan Patricof, Michael Kempner, Robert Zimmerman, Betsy Cohen, Jay Snyder and others.

Mr. Mook told the donors that the outcome in Nevada, a state he ran for Mrs. Clinton in the 2008 campaign, was hard to predict and that, depending on turnout, Mrs. Clinton could win by a lot or win or lose by a tiny margin, according to several donors who requested anonymity to discuss the private meeting. But Mr. Mook stressed that the map leaned in Mrs. Clinton’s favor as the race moved to South Carolina, where he was confident she would win, and that she would do well on March 1, when more states voted.

The collected fundraisers, who for years have bundled checks for Mrs. Clinton’s campaign, listened approvingly as Ms. White, who seemed especially frustrated, expressed bewilderment that the campaign’s mobilization of grassroots support had been eclipsed in the news media by Bernie Sanders’s criticism of Mrs. Clinton as the establishment candidate representing big money.

Mr. Mook, who had furnished the donors with a Washington Post clip about the campaign’s “small donor boom,” told the steering committee that he repeatedly told reporters about Mrs. Clinton’s small donors, but “they don’t listen.”

Donors also voiced some frustration with the lack of media scrutiny of Mr. Sanders, who they said was essentially getting a pass. They pressed Mr. Mook to demonstrate that the Vermont senator’s policy proposals were entirely implausible promises and that his responses to essentially all substantive questions drew on excerpts of his stump speech and rants about the “millionaires and billionaires.”

One donor also asked Mr. Mook to go after the youth vote. With a straight face, attendees said, the operative took the suggestion under advisement.
