Biden has made only one major border policy change since January—ending MPP.

That decision had virtually no effect on apprehensions, since Title 42 had already effectively replaced MPP in 2020. Just 1.19% of people encountered since Title 42 went into place were put into MPP. https://twitter.com/kausmickey/status/1385227329660604418

People like @kausmickey like to say "Biden created this crisis through his policies" but when you ask them to point to any specific policy changes and make a case for why that change made more people come, they end up just falling back on the idea that it's just about rhetoric.

Other policy changes that Biden made also did not change the 2020 status quo. For example, PACR, HARP, and the asylum cooperative agreements had already been suspended since March 2020 due to COVID, and Title 42 was already suspended for unaccompanied kids when Biden took office.

If your critique is that Biden is just being "too nice" by using welcoming rhetoric, then you have to admit that's it not about policy. And if you say it's about policy, then the onus is on you to explain why ending programs that applied to 0%-1.19% of people made a difference.

Of course, ending MPP was the right thing to do. The program had left 25,000 people stranded in Mexico with no end in sight, waiting in danger in an indefinite limbo.

But MPP was barely being used for new people and the idea that ending it triggered a "crisis" is laughable.
