Biden deserves credit for ramping up production and facilitating wider distribution, but there’s an enormous difference between building on a predecessor’s undeniable and important contributions and starting from nothing. Biden is doing the former and hoping most people believe it’s the latter.

If this is galling enough, it’s even worse to overturn a predecessor’s success and then falsely hold him responsible for the failure.

This is what Biden is doing at the border. He has begun to dismantle the policies that Trump put in place to control the migrant crisis of 2018-2019. As numbers predictably surge again, his Homeland Security secretary, Alejandro Mayorkas, has absurdly called out Trump for having “dismantled our nation’s immigration system in its entirety.”

Speaker Nancy Pelosi chimed in over the weekend, claiming that “what the administration has inherited is a broken system at the border.”

To the contrary, Biden has done the breaking. The Trump administration had found ways, entirely in keeping with our laws, to turn away illegal immigrants during the pandemic and to discourage bogus asylum-seekers by making them wait in Mexico while their claims are adjudicated.
