Kansas Secretary of State Kris Kobach, a leader in the anti-immigrant movement, said during his Sunday radio program that it’s possible that a Hispanic majority in the U.S. could conduct an “ethnic cleansing.”

Kobach made his remarks in response to a caller who asked, “What happens, if you know your history, when one culture or one race or one religion overwhelms another culture or race?”

Claiming that immigrant rights groups are “calling for the return of the Spanish territory, which could be almost half of the United States,” the caller warned, “When one race or culture overwhelms another culture, they run them out or they kill them. And it’s a bigger issue than just being Democrats. And they know in numbers, once the numbers are so bad, they can pretty much do whatever they want to do.”

“What protects us in America from any kind of ethnic cleansing is the rule of law, of course,” Kobach responded. “And the rule of law used to be unassailable, used to be taken for granted in America. And now, of course, we have a president who disregards the law when it suits his interests. So, while I normally would answer that by saying, ‘Steve, of course we have the rule of law, that could never happen in America,’ I wonder what could happen. I still don’t think it’s going to happen in America, but I have to admit, things are strange and they are happening.”

Earlier in the program, Kobach used a more subtle form of racial dog-whistle by accusing Democrats of “replacing American voters” with “socialist” Hispanic voters. While reading polls about political attitudes broken out by race, Kobach said that “if you look at it through an ethnic lens,” Democrats want to create a “a locked-in vote for socialism” by “replacing American voters with newly legalized aliens.”
