“I think this sort of bully demeanor may go over well in certain places,” Paul said Sunday on CBS’s “Face the Nation” after viewing a clip of Christie in a heated exchange. But, he added: “I grew up in the South, and we are ‘yes, ma’am’ and ‘no, sir’ and a little bit more polite.”

Paul said there was a time when he thought, “You know what, when he stands up and says things boldlym that’s kind of good — he’s not taking any flak. But there can be too much of that, too.”

The Kentucky Republican concluded: “I think there is a resurgence of people who want a little more civility and discourse.”
