Tea Party-backed Christine O'Donnell (R) took aim at New Castle County Executive Chris Coons (D) Tuesday night during an appearance on Fox News.
O'Donnell referenced an article Coons wrote in college in which he referred to himself as "a bearded Marxist."
Prompted by host Sean Hannity about Coons' years-old comment from Coons, she said, "if the media is going to attack me for statements I made in my 20s, that's fair game. He made some very anti-American statements, apologizing for America and calling himself a bearded Marxist."
Coons said earlier Tuesday on CNN that the reference was made in jest, calling it "a tongue-in-cheek reference to how Republicans on campus" viewed his transformation from a Young Republican to a Democrat.
O'Donnell referenced Senate Majority Leader Harry Reid's comments from last week made in an interview with The Hill, where he called Coons, "my pet."
"You have to wonder what kind of strange conversations went on that led to Harry Reid calling him his pet," said O'Donnell, who again painted herself as the victim of unfair attacks from her Democratic opponents and the national media.
On her own previous statements about having "dabbled into witchcraft" when she was in high school, O'Donnell said it was just a case of "teenage rebellion."
"Who doesn't regret the 80s to some extent?" O'Donnell asked.
She also pushed back against questions about her personal finances, claiming that she got behind on her mortgage because she took on "a pro-bono client" who was unable to pay her, presumably for public relations work.
The Tea Party favorite also said she's still holding out hope for an endorsement from her primary rival, longtime Rep. Mike Castle (R-Del.). Castle did not phone her after his loss last Tuesday and the Castle campaign quickly noted that there would be no endorsement of O'Donnell.
But the candidate said Castle did call on Friday to congratulate her and said of the possibility of an endorsement, "let's give him some time and hopefully he'll come around, because we need to unite the party."
The conservative commentator also hit the national media, saying she plans on following the advice of former Alaska Gov. Sarah Palin and shutting out the national press for the remainder of the campaign.
"It's interfering with my ability to campaign," O'Donnell said of the national media presence in Delaware. The candidate said her campaign is asking event organizers in Delaware to limit press access at some events, "because of the frenzy these things have become."
