“What the president keeps trying to do, he’s trying to run against somebody other than me,” Biden said Wednesday on a whistle-stop tour through Ohio and Pennsylvania. “I’ve said to the left, the right and the center exactly where I am on each of these issues.”

Biden’s debate comments, which reflected his commitment to winning over moderates in battleground states, prompted some concern among left-leaning activists, including at least one whose group reached out to his campaign to express his worries. But they were also followed by an embrace from some of the very liberal leaders Biden is keeping at arm’s length — including Ocasio-Cortez, one of the chief sponsors of the Green New Deal.

“Our differences are exactly why I joined Biden’s climate unity task force — so we could set aside our differences & figure out an aggressive climate plan to address the planetary crisis at our feet,” she tweeted late Tuesday, referring to one of the working groups Biden set up with liberals after capturing the nomination. Biden said Wednesday that he while they had not spoken recently, “I appreciated her endorsement.”

Her Green New Deal co-sponsor, Sen. Edward J. Markey (D-Mass.), sounded similar notes. “I support the Green New Deal and I’m voting for Vice President Joe Biden,” Markey said in a statement. “Donald Trump is wrong. The progressive left is with Joe Biden, and we will pass a Green New Deal.”
