Will the Democratic fiscal hawks challenge President Obama’s new stimulus proposal?

“When it comes down to it, they’ll vote the way their party leadership needs them to vote,” said Phil Kerpen, vice president for policy at Americans for Prosperity, a conservative organization that supports massive federal spending cuts. “We have not seen them actually kill any pieces of legislation, so the suggestion that it will happen now, well, I’m very skeptical about that.”

Blue Dog members said they will issue a more complete analysis of the plan once Congress reconvenes after September 13.

Update: The Hill reports that Sen. Michael Bennet, Colorado Democrat, is breaking with the Administration by opposing the infrastructure plan.

“I will not support additional spending in a second stimulus package,” Bennet said in a statement. “…Any new transportation initiatives can be funded through the Recovery Act, which still contains unused funds. Public-private partnerships that improve our infrastructure are a good idea, but must be paid for, should not add a dime to the deficit, and should be covered by unused Recovery Act dollars. We must make hard choices to significantly reduce the deficit.”
