John McCain said Sunday that the Republican presidential debates have turned into "mud wrestling," and lamented that the negativity is hurting the candidates.
"I think these continuing debates, and the tenor of the debates, which have turned into mud wrestling, have certainly raised the unfavorables of the candidates," McCain said on CNN's State of the Union. "I don't have any doubt about that."
He added that the Super PAC-driven attack ads are fueling the negativity, and ferociously attacked the Supreme Court for making them possible. Citizens United, McCain said, was a "disgraceful decision" in which the court "displayed a level of ignorance and arrogance that I don't think is with precedent."
