“Progressive firebrand Bernie Sanders jabbed his more moderate rivals on Saturday for taking campaign cash from billionaires as Democratic officials at some sites across Nevada were overwhelmed by long lines on the first day of early voting in presidential caucuses,” the AP reports.

Said Sanders: “Democracy is not candidates going to the homes of billionaires raising money.”

Joe Biden called on Bernie Sanders to accept greater accountability for tactics and rhetoric of his staunchest supporters and do more to discourage it, after what he called the “outrageous” threats on a prominent union that criticized his healthcare plan, NBC News reports.

Representatives of the powerful Culinary Workers Union said this week that supporters of the Vermont senator had “viciously attacked” its members after its leadership warned about the risk to their negotiated health plans under a Medicare for All system.

A new East Carolina University poll in South Carolina finds Joe Biden leading the Democratic primary field with 28%, followed by Bernie Sanders at 20%, Tom Steyer at 14%, Elizabeth Warren at 7%, Pete Buttigieg at 8% and Amy Klobuchar at 7%.

New York Times: “In the compressed and crucial weeks between the New Hampshire primary and Super Tuesday, Pete Buttigieg is moving aggressively to replenish his campaign coffers with an ambitious schedule of 10 fund-raisers held across six states in a 14-day period.”

Mike Bloomberg is considering making Hillary Clinton his running mate, a source close to his campaign has told Drudge Report.

Washington Post: “While allegations about Bloomberg’s comments and treatment of women have received notice over the years, a review by The Post of thousands of pages of court documents, depositions obtained under the Freedom of Information Act and interviews with witnesses underscores how Bloomberg and his company, Bloomberg LP, have fought the claims.”

“A number of the cases have either been settled, dismissed in Bloomberg’s favor or closed because of a failure of the plaintiff to meet filing deadlines. The cases do not involve accusations of inappropriate sexual conduct; the allegations have centered around what Bloomberg has said and about the workplace culture he fostered.”

Politico: “Interviews with two dozen South Carolina lawmakers, consultants and voters here suggests there are deep cracks in Joe Biden’s firewall state, where his campaign expects to turn his misfortunes around with a robust victory that highlights his broad-based support — particularly among African Americans.”

“No one denies the state has an affinity for the former vice president to Barack Obama. Biden boasts endorsements from nearly 200 black South Carolina community figures and state and national legislators, a testament to his decades-long relationships with many leaders here. And he’s led in every single public poll in the state over the past year.”

“But his advantage has gradually eroded.”

Russian pranksters claim they called Sen. Bernie Sanders pretending to be climate activist Greta Thunberg and offered Thunberg’s support to his campaign, the Daily Mail reports.

Mew York City Mayor Bill de Blasio, whose brief presidential campaign failed to get off the ground last year, endorsed Sen. Bernie Sanders of Vermont for the Democratic nomination, the New York Times reports.

“His choice is a reversal from four years ago, when he endorsed Hillary Clinton over Mr. Sanders, but it is not entirely unexpected. He said last summer that in retrospect, he believed Mr. Sanders would have won the 2016 election if nominated.”

Amy Klobuchar and Tom Steyer were stumped when asked during a televised interview in Nevada to name the Mexican president, the AP reports.

“It was really touching. I got phone calls, text messages from people who I’ve become friends with over the last number of months, including Cory, Kamala, Beto and people that have reached out on a personal level. They’re not trying to get anything out of it. It’s just sort of sharing your human experience.”
