The U.S. Senate gave final approval to a small jobs bill today by a vote of 68-29. Eleven Republicans and the Senate’s two independents joined 55 Democrats (including Iowa’s Tom Harkin) to pass the bill. The only Democrat to vote no was Ben Nelson of Nebraska (roll call here). The motion to invoke cloture on this jobs bill passed the Senate on Monday by a 60-31 vote, with six Republicans voting with all Democrats but Ben Nelson (roll call here). Senator Chuck Grassley voted with the Republicans who tried to filibuster the bill on Monday and with those who opposed the bill today. From the Washington Post:

The centerpiece of the bill is a new program giving companies a break from paying Social Security taxes for the remainder of 2010 on any new workers they hire who had been unemployed for at least 60 days. Employers would also get a $1,000 tax credit for each of those workers who stays on the payroll for at least one year.

Aside from that program, the measure includes a one-year extension of the law governing federal transportation funding, and would transfer $20 billion into the highway trust fund. The bill also extends a tax break allowing companies to write off equipment purchases, and expands the Build America Bonds program, which helps state and local governments secure financing for infrastructure projects.

Last month the Senate approved a similar jobs measure; Grassley voted no at that time as well. After the House made minor changes to the legislation, the bill had to clear the Senate again before going to the president’s desk.

Most House Democrats support a larger job-creation bill with more money for infrastructure projects, but there may not be 60 votes in the Senate for such a measure.
