Dara Lind relays further evidence that the answer is yes:
[T]he fact that, as of August, fewer children are arriving this year than arrived at the same time last year indicates that this isn’t just a seasonal slowdown. It really looks like the flow of children into the country has slowed down to nearly manageable levels for the time being.
Indeed, the US government is no longer overwhelmed by the flow. Border Patrol officers are legally required to turn unaccompanied children over to the Department of Health and Human Services no more than 72 hours after they’re apprehended. At the worst parts of the crisis this summer, they weren’t even close to meeting that deadline — they took an average of more than three weeks. Now, according to Deputy Homeland Security Secretary Alejandro Mayorkas, they’re back to normal, turning kids over to HHS well within the 72-hour window.
In another post, Lind contrasts Ted Cruz’s border rhetoric with this new reality:
Cruz warned explicitly that promises of “future amnesty” would only make the problem worse. On June 30th, President Obama gave a Rose Garden speech explicitly promising to take further executive actions on immigration. Those promises included, in Cruz’ words, “plans to give amnesty to millions more who arrived in our country illegally.” Cruz said that because of those plans, Obama was responsible for the border crisis — and predicted that “the surge of unaccompanied children trafficked to the United States by drug cartels and transnational gangs will not ebb until Congress restrains the President from taking any further executive action.”
That’s not what happened. The surge has ebbed — largely due to law-enforcement efforts by US and Mexican authorities, and Mexican efforts to catch children traveling through Mexico before they arrive in the US.
