Rick Santorum claims CNN's Kate Bolduan thinks all Republicans are racists -- and she obliterates him

Rick Santorum pushed CNN host Kate Bolduan too far on Thursday when he said that she thinks all Republicans are racist.

In a discussion about Trump's latest ad, which has been strongly criticized as some of the most racially-charged political messaging in decades, Santorum tried to make the case that it was "nothing new".

"This is new," Bolduan countered. "That campaign video that the president put out is something we haven't seen really in decades, in the tone, the tenor, just the racist overtones of it all."

Santorum immediately melted down, and tried to pivot to "blame the media".

"Quit doing this, Kate," he shouted, screwing up his face. "This happens on this network just way too much, that anybody that disagrees on a public policy issue is a racist."

The gambit didn't work: in fact, it just made Bolduan angry.

"Come on. You and I have known each other long time, don't paint me with broad brush strokes like that," she retorted, visibly frustrated as the former senator continued trying to talk over her. "'Every time there's a policy discussion'? I'm not calling Republicans racist. That's not what I'm saying at all."
