WASHINGTON (CNN) -- Jim Gilmore said several of his fellow Republican candidates have been "very liberal in characterizing themselves as conservatives, particularly on the issues of abortion and taxes and health care."

Asked by moderator Chris Wallace about his frequent use of the phrase "Rudy McRomney," a derogatory term phrased by some conservative activists to refer to Rudy Giuliani, John McCain and Mitt Romney, Gilmore took a swipe at Rudy Giuliani's abortion stance, Mike Huckabee's tax record, and Mitt Romney's health care record.

"Did I get left out?" John McCain asked.

"I'll come back," Gilmore replied.

Asked to respond, "I think Rudy McRomney wouldn't make a bad ticket," Giuliani said, "and I kind of like the order."

Mike Huckabee later joked he that if he's going to be hit, he wouldn't mind being mentioned by name, or partially by name.

"Well, it's a form of flattery to be attacked. But I wish my name would get in the moniker that Governor Gilmore is putting out there. I could use the bump."
