The fate of a tax credit that advocates say is needed to maintain tens of thousands of wind energy jobs will be decided during high-stakes, last-minute negotiations between President Obama and House Republicans over fiscal issues.

The credit was first signed by President George H.W. Bush and backed by a number of prominent Republicans. But some conservative House Republicans objected to the extension of the latest form of the credit this summer, arguing it is wasteful spending. Their cause was taken up by the party's presidential nominee, Mitt Romney, who argued the credit should expire.

Still, Republicans governors Terry Branstad of Iowa and Sam Brownback of Kansas joined Democratic governors on Tuesday's call urging the credit's extension. They said they represented a bipartisan group of 28 governors who back the tax break.
