Tucker Carlson (Credit: AP/Richard Drew) It seems that Fox News host Tucker Carlson has never heard of gentrification. On Monday night, “Tucker Carlson Tonight” featured a segment lamenting the “changing demographics in America.” It was meant to be a commentary on how one town was seeing more Hispanic immigrants, but Tucker was opaque enough to make a larger point about demographics. “A recent piece in National Geographic tells you a lot about demographics in America and how bewilderingly fast they’re changing without any real public debate on the subject,” Carlson said.
