(CNN)The Democrats' budget reconciliation package, which gained more heft after West Virginia Sen. Joe Manchin agreed to add back several climate and tax provisions, was passed Sunday by the Senate on a party-line vote.

It won the critical support of Arizona Sen. Kyrsten Sinema, who demanded several changes be made. It now goes to the Democratic-controlled House for approval before President Joe Biden can sign it into law.

Still, the effort remains a mere shadow of the sweeping $3.5 trillion reconciliation package that the majority party initially floated last year.

After torpedoing the inclusion of any climate or tax provisions in mid-July, Manchin, a moderate Democrat, reversed course. The measures join a handful of important but narrow provisions to lower prescription drug prices and to extend enhanced Affordable Care Act subsidies for three years.

Gone are the creation of a universal pre-K program, an extension of the enhanced child tax credit, an expansion of Medicare benefits, the establishment of a federally funded paid family and sick leave program and many other provisions aimed at broadening the nation's social safety net..
