On the presidential debate stage Tuesday, former President Donald Trump spewed reliably racist and lie-riddled diatribes about towns being taken over by “millions of people pouring into our country from prisons and jails, from mental institutions and insane asylums.”

Vice President Kamala Harris, for her part, didn’t bother to counter the sentiment, the central ideological violence at the heart of Trump’s message. Harris, albeit in the predictably moderated tones of a Democratic border authoritarian, upheld the right-wing lie that immigration — the migration of poor people, that is — should be stopped.

Both candidates purported to offer diametrically opposed visions for the country’s future. When it came to immigration and the U.S. border, however, only one narrative was available throughout the night: Immigration is a social ill, if not a criminal endeavor, to be deterred as much as possible.
