“It’s a lesson for all Democrats who are eager to replace Trump,” said former Chicago Mayor Rahm Emanuel. “There was no skimping on the progressive agenda and it was the worst performance in two decades. It’s not just economics. You have to have a candidate and a message that’s close to the zeitgeist of the moment — not just a grab bag of giveaways.”

The thoroughness of Corbyn‘s thrashing revived the longstanding debate within the party over just how ambitious the Democratic agenda should be, and provided fresh ammunition for the arguments of moderates who contend that if the party backs Bernie Sanders or Elizabeth Warren, the primary’s leading progressives, they’ll lose the Rust Belt and perhaps even elsewhere.....

"Corbyn was basically a satellite project for Bernie world. If there is one lesson to be gleaned from the devastating loss across the pond, it's that we need more than just soaring rhetoric backed up by bravado of organizing,” said Murshed Zaheed, a Megaphone Strategies partner and former Harry Reid aide backing Warren. “We need to have leaders who have crystal-clear analysis of how to solve problems and leverage power to achieve those solutions. Corbyn never appeared to be a candidate with any sound plans on how to move U.K. forward.”

Before the polls closed on Thursday, Sanders’ national organizing director, Claire Sandberg, had tweeted that the “Bernie team says #VoteLabour” with a picture attached of campaign staff. Rep. Alexandria Ocasio-Cortez, a top congressional ally who has campaigned with Sanders in Iowa, also tweeted in support of Labour. Two 2016 aides to Sanders, Becky Bond and Zack Malitz, had traveled to London earlier this year to help the pro-Corbyn group Momentum as well.
