One of Ann Coulter’s new favorite talking points, which she uses in her new anti-immigrant book “Adios America!” and has repeated in various media interviews, is that the U.S. has “taken in one-fourth of Mexico’s entire population.”

Earlier this week, Politifact gave that claim a “Pants on Fire” rating , noting that Coulter is comparing the number of people of Mexican heritage living in the U.S. — including people who’s families have been in the country for generations — with the current population of Mexico, which is kind of like saying that the large population of Irish Americans means that the U.S. has “taken in” Ireland’s population seven times.

But this, of course, is all part of the media’s persecution of Ann Coulter, at least according to her friend Joyce Kaufman, a conservative radio host in Florida, who cited the Politifact story in an interview with Coulter yesterday as an example of the media “going crazy trying to debunk facts.” The Mexican-American citizens Politifact mentions, Kaufman said, are “anchor babies” and therefore “should not count” as being Americans.

Coulter agreed, saying that granting birthright citizenship to the children of undocumented immigrants — something consistent with the history of the 14th Amendment — was an “invention” of the “mentally delusional” Supreme Court Justice William Brennan in the 1980s.

“This doesn’t go back to the 14th Amendment,” she said, “this is the invention of one mentally delusional Supreme Court justice. And he’s turned the most precious possession in the universe, citizenship in this wonderful country, into a game of tag with the border control. If they don’t catch you, you get to drop the baby and say, ‘Ha ha ha, I just had the baby and you can’t do anything!’ It’s madness.”
