Yet legislation encoding this deal has yet to be written, much less passed. Chuck Schumer, the Senate majority leader, said after the filibuster was evaded that he wanted the infrastructure bill and a budget resolution to pass before the August recess. The budget resolution is necessary for the Democrats to begin the filibuster-proof process known as reconciliation, by which they want to enact a $3.5trn bill to finance child care and education and to confront climate change.
Republican senators do not want to be seen as enabling the budget bill by supporting the infrastructure one. Yet for many Democrats, including the House speaker, Nancy Pelosi, the two are yoked together. Ms Pelosi has said she will not consider the bipartisan bill until the Senate passes the reconciliation package.
For Mr Biden, the challenge ahead within his party is formidable. Alexandria Ocasio-Cortez, a progressive force in the House, reacted with fury on Twitter, threatening to torpedo the infrastructure deal and noting the Senate negotiators were all white: "Good luck tanking your own party's investment on childcare, climate action, and infrastructure while presuming you'll survive a 3 vote House margin—especially after choosing to exclude members of colour from negotiations and calling that a 'bipartisan accomplishment'," she wrote.
Now, Mr Jennings notes, "Joe Biden is going to Alexandria Ocasio-Cortez and saying, 'I need you to vote for this thing that Mitch McConnell is for.'" If the infrastructure bill then fails, it will be the progressives, not Mr McConnell and his Republicans, who will have crushed Mr Biden's bipartisan dream.
