Democrats could end up being "slaughtered" in the 2010 midterms, one of President Obama's top campaign aides said today.

"I think that there is a real shot we are going to get slaughtered in elections this fall if we aren't leading the efforts to reform Washington," Steve Hildebrand, Obama's deputy national campaign director in 2008, told CNN. "We campaigned in '06 and '08, and if voters don't see that change, we haven't lived up to that promise."

Hildebrand, who didn't join Obama's White House after the election, is pushing Democrats to do more on ethics reform. He's urging Congress to approve an outside watchdog agency to handle ethics complaints, and pushed the matter in a meeting yesterday with David Axelrod.

"We went after that culture of corruption, and I don't believe there is a culture of corruption, but I do believe there is an image problem that Washington in general has to deal with," Hildebrand said. "And Democrats are in trouble now and if they don't do anything."
