The Senate has finally opened the door to debate on a newly reached bipartisan deal on infrastructure – one that is far less expensive and over-reaching than what was desired by Biden and the Dems.

Though the legislation is still unfinished and failed just a week ago, more than a dozen Republicans took the plunge and voted to break an initial filibuster on the bill. Among them was Senate Minority Leader Mitch McConnell (R-Ky.), who has previously said “100 percent” of his focus was on standing up to Biden’s agenda.

The $1.2 trillion deal was reached earlier in the day when by a bipartisan group of senators. Reports on Wednesday cited lead GOP negotiator Sen. Rob Portman (R-Ohio), who said, “we now have an agreement on the major issues, and we’re prepared to move forward.”

However, the bill is not fully written yet.

“This is also important to demonstrate that Republicans and Democrats can come together for the really hard stuff to negotiate in good faith,” stated Sen. Lisa Murkowski (R-Alaska). “And to broker an agreement that is not going to work just for Republicans or Democrats. It is going to work for the country.”

But even as the Senate agreed to begin considering the bipartisan framework, the final passage remains uncertain. Republicans will demand amendment votes and input on the bill, and it will once again face a 60-vote hurdle to close debate. The Senate may even work through the weekend to make progress on the proposal and its $550 billion in new spending as of August recess approaches.

“I want to commend the group of senators who worked with President Biden,” said Senate Majority Leader Chuck Schumer (D-N.Y.) after the vote. “My goal remains to pass both the bipartisan infrastructure bill and a budget resolution period. Both. It might take some long nights, it might eat into our weekends, but we are going to get the job done. And we are on track.”

Ahead of the vote, Schumer pleaded for full party support to advance the bill, which many progressives have reservations about, at lunch for all 50 Democrats, according to Senate Majority Whip Dick Durbin. Afterward, Schumer professed confidence that the Senate was finally ready to move forward.

Wednesday’s breakthrough comes after a month of brutal negotiation and on again off again deals on infrastructure. In the end, it took weeks to finalize the details between a bipartisan group of 10 senators and the White House, and even on the day of the vote, the bill was still being written.

Meanwhile, a key Democrat said Wednesday that she will not support the proposed $3.5 trillion spending plan that her party had hoped to ram through the Senate without support from Republicans.

Sen. Kyrsten Sinema (D-Ariz.) said in a statement, “I support many of the goals in this proposal to continue creating jobs, growing American competitiveness, and expanding economic opportunities for Arizonans … I do not support a bill that costs $3.5 trillion.”

The announcement means Democrats will likely need to reduce the scope of the legislation to secure the support of Sinema and her fellow moderate, Sen. Joe Manchin (D-W.Va.). With the Senate split 50-50, Democrats cannot afford to have a single member of their conference defect if they want to pass a so-called “reconciliation” bill with just 51 votes.

The $3.5 trillion plan, backed by socialist Senate Budget Committee Chairman Bernie Sanders (I-Vt.), would have called for a massive infusion of cash for education initiatives like universal pre-kindergarten, Medicare expansion, efforts to counter the effects of climate change, and more.
