O'Donnell fired back the next day in an interview with ABC's George Stephanopoulos.

O'Donnell, who had been laughing throughout Stephanopoulos's questions, did not answer Rove's charges directly but simply insisted, "Everything that he's saying is unfactual. And it's a shame, because he's the same so-called political guru that predicted I wasn't going to win. ... He's eating some humble pie, and he's just trying to restore his reputation."

"When we started gaining momentum and we started gaining credibility in this race, it made the Republican establishment look like lazy people who did not care about their principles," O'Donnell continued. "I was ahead in the general election according to Rasmussen before this Republican cannibalism started. ... So if they were serious about winning, we could repair the damage done and move forward."

More recently, O'Donnell told the Wilmington, Delaware Rotary Club that she was willing to stand against her own party.

"If you want a senator who has had to fight her own party and is still fighting her own party," she said, "please vote O'Donnell for U.S. Senate."

But in an interview aired on ABC Sunday, Christine O'Donnell nearly begged establishment Republicans to come to her rescue.

"We're asking the National Republican Senatorial to help us shine a spotlight on my opponent's negative record," said O'Donnell.

"We're hoping that the National Republican Senatorial Committee will help us. But it's two and a half weeks left, and they're not," she said.

Even within the Tea Party, O'Donnell's support is not unanimous. Tea Party supporter Linda Conway told ABC that she was going to vote for Democratic candidate Chris Coons.

"I feel that the girl has no experience," said Conway. "For some reason I just have [a feeling] that she's almost like a front for someone and I just don't feel that this young lady has the control and the smarts to get us out of this jam that we're in at this time and I feel that coons with his experience does."
