Here’s a mental exercise: If you had to invite a group of people to live in your house, would you pick the people coming from the mansion in a similar neighborhood to yours or would you pick the folks in the broken home that always have the police parked out front?

Democratic presidential candidate Bernie Sanders did the inexplicable at Thursday’s primary debate and picked the latter.

The Vermont senator probably didn’t know it, but he laid out the case for why the U.S. should have no tolerance for absorbing the hundreds of thousands of Central American migrants making their way here and overwhelming our border.

Here’s Sanders’ full quote at the debate when he was asked about our collapsing immigration system:

We got to look at the root causes and you have a situation where, Honduras, among other things, is a failing state. Massive corruption. You’ve got gangs who are telling families that if a 10-year-old does not join that gang, that family is going to be killed. What we have got to do on Day One is invite the presidents and the leadership of Central America together. This is a hemispheric problem that we have got to address.

This was of course after every single Democrat on stage said we should be welcoming every person south of our border in to the country, and, in the words of former Ohio Gov. John Hickenlooper, “providing” them with “shelter, food, clothing, and access to medical care.”

There are actual Americans who can’t get those things on their own, let alone from the government, and yet Sanders et al. want to give these benefits to the people coming from “a failing state” that breeds violence, crime, and corruption.

Bernie Sanders didn’t know it, but he made the best case possible for turning all of those people away the second they arrive.
