“In 30-plus years of politics, I’ve never seen this level of doom. I’ve never had a day with so many people texting, emailing, calling me with so much doom and gloom,” said Matt Bennett of the center-left group Third Way after Sanders’ win in Nevada.

Bennett said moderates firmly believe a Sanders primary win would seal Donald Trump’s reelection. “It’s this incredible sense that we’re hurtling to the abyss. I also think we could lose the House. And if we do, there would be absolutely no way to stop [Trump]. Today is the most depressed I’ve ever been in politics.”…

“For the establishment, I think it’s Joe or bust,” said Simon Rosenberg, New Democrat Network president, who served as a senior strategist for the Democratic Congressional Campaign Committee in 2018.

“Biden is the only one who has a path to defeat Bernie. It would involve him winning South Carolina and then performing well enough in the early March states to keep the race competitive,” Rosenberg said. “I don’t think Bloomberg can recover quickly enough from the hits he’s taken in recent days to remain competitive or win the nomination.”
