In a protracted wrangle over the $3.5 trillion federal investment, lawmakers narrowly approved Democrats’ budget resolution on a 50-49 vote in a massive victory for US President Joe Biden.

Passage came despite an avalanche of Republican amendments intended to make their rivals pay a price in next year’s elections for control of Congress.

In two weeks, House leaders will vote on the fiscal blueprint regarding disbursing the $3.5 trillion over the next decade.

Final congressional approval, which seems certain, would protect a subsequent bill actually enacting the outline’s detailed spending and tax changes from a Republican filibuster in the 50-50 Senate, delays that would otherwise kill it.

Senate Budget Committee Chairman Bernie Sanders, I-Vt., said the measure would help children, families, the elderly and working people, and more.

“It will also, I hope, restore the faith of the American people in the belief that we can have a government that works for all of us, and not just the few,” he said.

Republicans were wary that Democrats’ proposals would waste money, raise economy-wounding taxes, fuel inflation and codify far-left dictates that would harm Americans.

They were happy to use Sanders, a self-avowed democratic socialist, to try tarring all Democrats backing the measure.

The Senate turned to the budget minutes after it approved the other big chunk of Biden’s objectives, a compromise $1 trillion bundle of transportation, water, broadband and other infrastructure projects. That measure, passed 69-30 with McConnell among the 19 Republicans backing it, also needs House approval.

Senate Majority Leader Chuck Schumer, D-N.Y., assured progressives that Congress will pursue sweeping initiatives going beyond the infrastructure compromise. Democrats control the House but only narrowly.

“To my colleagues who are concerned that this does not do enough on climate, for families, and making corporations and the rich pay their fair share: We are moving on to a second track, which will make a generational transformation in these areas,” Schumer said.

One amendment may have boomeranged after the Senate voted 99-0 for a proposal by freshman Sen. Tommy Tuberville, R-Ala., to curb federal funds for any municipalities that defund the police. That idea has been rejected by all but the most progressive Democrats, but Republicans have persistently accused them anyway of backing it.

In an animated, sardonic rejoinder, Sen. Cory Booker, D-N.J., called Tuberville’s amendment “a gift” that would let Democrats “put to bed this scurrilous accusation that somebody in this great esteemed body would want to defund the police.” He said he wanted to “walk over there and hug my colleague.”

Republicans claimed two narrow victories with potential long-term implications, with West Virginia Sen. Joe Manchin, one of the chamber’s more conservative Democrats, joining them on both nonbinding amendments.

One indicated support for health care providers who refuse to participate in abortions. The other voiced opposition to teaching critical race theory, which considers racism endemic to American institutions. There’s scant evidence that it’s part of public school curriculums.

The budget blueprint envisions creating new programs including tuition-free pre-kindergarten and community college, paid family leave and a Civilian Climate Corps whose workers would tackle environmental projects.

Medicare would add dental, hearing and vision benefits, and tax credits and grants would prod utilities and industries to embrace clean energy. Child tax credits beefed up for the pandemic would be extended, along with federal subsidies for health insurance.

Besides higher taxes on the wealthy and corporations, Democrats envision savings by letting the government negotiate prices for pharmaceuticals it buys, slapping taxes on imported carbon fuels and strengthening IRS tax collections. Democrats have said their policies will be fully paid for, but they’ll make no final decisions until this fall’s follow-up bill.
