The U.S. Senate passed a scaled-back jobs bill today by a 70-28 vote (roll call here). 57 of the 59 Senate Democrats voted for the bill; Ben Nelson of Nebraska voted no and Frank Lautenberg of New Jersey was absent. 13 Republicans voted for the bill. Five of them helped Democrats break a Republican filibuster on Monday: Olympia Snowe and Susan Collins of Maine, Scott Brown of Massachusetts, and the retiring Kit Bond of Missouri and George Voinovich of Ohio. Two Republicans who were absent for Monday’s cloture vote also voted yes today: Orrin Hatch of Utah and Richard Burr of North Carolina. Six other Republicans tried to block this vote from going forward on Monday but turned around and voted for the bill today: Lamar Alexander of Tennessee, Thad Cochran and Roger Wicker of Mississippi, James Inhofe of Oklahoma, George LeMieux of Florida, and Lisa Murkowski of Alaska.

Senate Democrats and the media are calling this a $15 billion jobs bill, but David Dayen notes, it’s really a $35 billion measure: “the extension of the Highway Trust Fund would add $20 billion for infrastructure projects, but because of the way it’s financed, through a fund shift, it doesn’t count as an expense.”

In addition to the highway fund money, the main features of the jobs bill are a tax credit for small businesses that hire new workers, “Build America Bonds” that help state and local governments to borrow money, and a provision to allow small businesses to write off more expenses.

Senator Chuck Grassley voted against today’s bill and against the cloture motion on Monday. He and Senate Finance Committee Chairman Max Baucus had agreed on a different jobs bill, which Senate Majority Leader Reid abandoned. In a statement submitted to the Senate record on Monday, Grassley slammed Reid’s “disregard for bipartisanship” and noted that tax-extending provisions in the Baucus-Grassley bill had enjoyed broad support from both parties in the past.

The House passed a larger jobs bill in December that included many of the tax-extending provisions Reid omitted from the Senate bill.

Mark Zandi, chief economist at Moodys.com, said last week that Reid’s jobs bill was “a good first step” but not nearly large enough to address the unemployment problem:

A failure to provide additional funding to struggling states, for example, would lead to job losses that would “overwhelm” all the other job-creating efforts being tried, he said. And while the Schumer-Hatch tax credit would create between 200,000 and 300,000 new jobs, Zandi estimated, that number is a drop in the bucket relative to the roughly 11 million new jobs needed to get the country back to pre-recession jobless levels.

Reid has promised to introduce more jobs-creating legislation soon. Meanwhile, House Speaker Nancy Pelosi will try to move quickly on the bill the Senate just approved, Roll Call reported.
