• The main factor appears to be Mexico’s government bottling people up, even as large numbers continue arriving in the country’s south.
• “Shutting down” asylum, as President Biden is considering trying to do by executive order, could bring numbers down in the short term but—as we saw with Title 42—won’t have a lasting effect.
• Crackdowns will always fail. The way to a solution runs through overhauling the creaky U.S. asylum system.
