Former Republican presidential candidate Rick Santorum says that Vice President Joe Biden and President Barack Obama are “dividing this country” by playing the race card and using words like “y’all.”

CNN host Jim Acosta on Sunday asked if it was fair for Romney to complain about the tone of the campaign when he had run negative ads during the primary that called Santorum a “lightweight” and suggested that the former Pennsylvania senator was not “ready to be president.”

“I think what he’s talking about is the tone of the Obama campaign, which is divisive,” Santorum explained. “To go out and do what [Obama's] doing and divide this country, and he is, and it’s class warfare at its worst.”
