Aides to Santorum told ABC News on Sunday that the former Pennsylvania senator is fed up with the negative attacks coming from the campaigns of those two opponents and from their allies. He will hold a press conference to make his displeasure known after his first campaign event of the day on Monday.

“It’s time for these negative, false attacks to stop — enough is enough,” Santorum’s communications director Hogan Gidley said in an interview with ABC News. “Mitt Romney and Ron Paul both tried these kinds of tactics in other states and they tried these same type of tactics four years ago. It’s time for Rick to set the record straight and tomorrow he will.”…

He told a crowd of about 200 at a restaurant in Florence, S.C. that he expects those kind of campaign tactics from President Obama, but “I don’t expect that from a Republican running for president.” He added that purposely misleading the voters of South Carolina” is “just yuck.”
