(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..
