The effects of illegal immigration aren't that different from those of legal immigration —an illiterate Central American farmer with a green card is just as unsuited for a 21st-century economy as an illiterate Central American farmer without a green card.

And they are much more skeptical of the very idea of having immigration limits, whereas the public - again, independents and Democrats, as well as Republicans, although not necessarily all in the same proportions - have a much stronger sense of the American government and American law having responsibility to Americans specifically rather than to people around the world. So the polarization is up versus down, not really right versus left.

Well, because we're talking here about people who've been ordered deported and the administration has done nothing about actually making sure that they go home. This is theater, I think, for two audiences - one probably for the American public to some degree, to make it seem as though the administration is taking this renewed surge of Central Americans seriously.

Well, enforcement theater is OK if it's reality theater. In other words, obviously, you want to make it clear, you want to make people see that the law is being enforced.

But the other audience, I think, is people in Central America because since last summer, they've been running ads down there - the United States government has - don't come, it's dangerous. You will be immediately deported. That's literally what it says in Spanish.

But the question is - are we deporting a couple hundred people for show or are we actually making a serious effort to remove everybody who's got a final order of removal? When I say enforcement theater, what I mean is a kind of pretend enforcement.
