In an Oval Office meeting with House progressives last week, Joe Biden made a joke about how much had changed in his long career: “I used to be called a moderate,” the president mused. He was, at that moment, trying to mediate a Democratic Party struggle between the left-wing lawmakers sitting before him and the moderates he had hosted a few hours earlier. When the meeting ended, Biden pulled aside Representative Pramila Jayapal of Washington State. He thumbed through a folder of papers he was holding. Eventually, Biden handed Jayapal a copy of the speech he delivered to Congress in April, in which he laid out the economic vision he wanted to enact—the ambitious agenda to expand the social safety net over which Democrats are currently haggling.
