"On a lot of these issues it is hard to know exactly where he stands, and people need to ask that," she told supporters at a coffee shop in New Hampshire yesterday.
Clinton and Obama now have overlapping messages as they try to stir up support.
"I'm fired up and I'm ready to go," Clinton cheered to a crowd in Davenport, Iowa, on Thursday.
"Are you fired up? Are you ready to go? Fired up! Ready to go!" Obama chanted to a younger crowd that rallied back in Greenfield, Iowa, in December.
Clinton is not the only candidate who is trying to steal back the limelight in one long weekend.
"The status quo is yesterday. And change is tomorrow. And tomorrow begins today, right here in New Hampshire," said John Edwards, who edged out Clinton forsecond place in Iowa.
Edwards insists he's no dark horse. His new slogan, perhaps the oddest of the campaign so far, compares himself to a thoroughbred racehorse. "We are Seabiscuit. I am the people's candidate," Edwards said in Manchester, N.H., today.
