Friday on Fox News, Tucker Carlson questioned Lindsey Graham's claim that "America is an idea" and "not defined by its people."

"According to Lindsey Graham, you could take our entire population and swap it out for 320 million, I don't know, Chinese or Indians or Africans or Canadian or people from New Zealand, and the place would be no different, so long as the idea was still there," Carlson said. "Does anyone actually believe that?"
