No-drama budget vote: How can this be? NEW: "Nothing's going to be perfect in this world," Democratic senator says The bill aims to avert further government shutdowns for the next two years Concerns include reduced military benefits, a failure to extend jobless benefits Washington (CNN) -- For the first time in what seems like ages, Congress is poised to give final approval to a government spending plan without resorting to last-minute brinksmanship such as midnight negotiations to prevent an imminent government shutdown. The Senate is expected to pass the compromise federal budget framework Wednesday and send it to President Barack Obama, who has signaled his support. Final approval in the Senate requires a simple majority of 51 "ayes" in the Senate, which voted 67-33 on Tuesday to overcome a Republican filibuster. Last week, the budget plan easily passed the House on a 332-94 vote, with solid majorities of both parties supporting it. While Wednesday's Senate vote will be closer, a CNN count showed the deal hashed out by the budget committee leaders in each chamber appeared to have the necessary backing for final approval. It would guide government spending into 2015 and defuse the chances of a shutdown like the one in October that generated public anger against Congress, particularly conservative Republicans blamed for the impasse. Budget deal: Winners and losers An ABC News/Washington Post poll released Tuesday showed that 50% of respondents supported the budget plan while 35% opposed it. Some Senate Republicans have said the most important issue at the moment is to lower the budget deficit, even if only by a small percentage, and avoid another damaging scenario like the 16-day government shutdown in October. GOP Sen. Ron Johnson of Wisconsin said he wanted "to make sure we avoid any additional government shutdowns." Democratic Sen. Jon Tester of Montana said his side dislikes some elements of the agreement, but that's life in divided government when the Senate and House are controlled by different parties. "We need to get some certainty, and that's what this does," he said Tuesday night on CNN, adding: "Nothing's going to be perfect in this world. It's called compromise. Budget compromise Republican Rep. Paul Ryan of Wisconsin and Democratic Sen. Patty Murray of Washington, the budget committee leaders in both chambers, negotiated the deal that eliminates some forced spending cuts known as sequestration that both sides disliked while reducing the deficit by more than $20 billion in coming years. Final congressional approval would be a rare example of budget bipartisanship after two years of seemingly endless confrontation and acrimony reflecting the differing ideologies of the two sides. Republicans, especially the conservative tea party wing that emerged in 2010, want to drastically shrink the government as the main tool for reducing federal deficits and debt. Democrats insist on protecting the social safety net for the most vulnerable Americans, such as Social Securityi, Medicare and Medicaid. With midterm elections next year, the Washington dysfunction has spawned public disgust reflected by polls showing support for Congress around record low levels. The budget agreement, which was months in the making, eases spending caps while softening the impact of the sequestration cuts on defense and nondefense programs. It sets overall spending figures through fiscal year 2014, which started on October 1, as well as fiscal year 2015, with the intent of putting off any further congressional budget stalemate until after the November election. The strong vote in the sharply divided House last week brought a collective sigh of relief among supporters, who initially thought it would sail through the Senate, where bipartisanship has been more the norm. However, some Senate Republicans -- including several in leadership positions -- came out against the bill. Republican Sen. Lindsey Graham of South Carolina and others complained that the plan reduces some military benefits. While Democrats support the bill, many had concerns. "There's over a million people now who cannot find a job, out of work, and right at this time of year their unemployment insurance is being cut off," he told Radio Iowa last week.
