WASHINGTON – The House of Representatives approved the fiscal 2011 bipartisan deal Thursday by a vote of 260-167. The Senate is poised to pass the measure Thursday and fund the government through September.

As GOP leaders feared, Democratic support was necessary to push the measure over the top as 59 Republicans defected. Eighty-one Democrats joined 179 Republicans in helping pass it.

The accord negotiated last Friday by Speaker John Boehner (R-OH), President Barack Obama and Senate Majority Leader Harry Reid (D-NV) would cut federal spending authority by $38 billion from 2010 levels. But its deficit savings for 2011 are projected at just $352 million, according to the Congressional Budget Office.

Boehner faced the prospect of a last-minute tea party exodus as the CBO figure drew fire from prominent conservatives, but managed to hold together a large enough GOP coalition to ensure its passage.

Correction: An original version of this article incorrectly labeled Sen. Reid a Republican.
