(ABC NEWS) Lanny Davis, a former top adviser to President Bill Clinton, today issued a scathing rebuke to a controversial new Democratic super PAC ad that ties Mitt Romney to a woman’s death from cancer.

“I’m pretty sad for our country that we have presidential candidates engaging in sophomoric — and that’s a compliment — sophomoric name calling,” Davis said in an interview on WMAL radio in Washington.

Davis says both Romney and Obama, and their supporters, have sponsored ads “that make us all want to take a shower.”  But when it comes to the cancer ad, he said the pro-Obama super PAC Priorities USA Action has gone too far.
