Democrats are approaching the end of the year with little to show for their efforts at passing new laws protecting voting rights, reforming the immigration system, expanding the social safety net, fighting climate change and more.

With a tenuous 50-seat majority in the Senate and several moderate lawmakers who continue to object to their plans, the party is finding it hard to make progress on much of their ambitious legislative agenda.

Were frustrated and disappointed, said Dick Durbin (Ill.), the No. 2 Senate Democrat, told reporters on Thursday.

Democrats had hoped to pass the Build Back Better Act, their $1.75 trillion social spending and climate package, by Christmas Day. But negotiations between Manchin and President Joe Biden are said to be going poorly , with sharp disagreements over the child tax credit and other provisions.

Manchin got an earful from his colleagues on the Senate floor on Thursday, including from Sen. Michael Bennet (D-Colo.), a leading advocate of the monthly child tax credit payments, which will lapse next month without congressional action. But the discussions didnt appear to yield any progress.

Biden issued a statement on Thursday that conceded what congressional Democratic leaders did not: More work needed to be done to pass the bill.

My team and I are having ongoing discussions with Senator Manchin; that work will continue next week, Biden said. Leader Schumer and I are determined to see the bill successfully on the floor as early as possible.
