On Friday, February 24, I was a guest on Making Money with Charles Payne on the Fox Business Network to discuss sanctuary cities. I don’t think I gave the host the answer he was looking for. He asked me how could it be that the Mayor of San Francisco could resist the President with respect to enforcing federal policy. I explained the doctrine of commandeering, citing Justice Scalia’s opinion in Printz, and gave the example of local sheriffs refusing to enforce federal gun control laws. I hope I got through to a few people in the audience–federalism exists, even if it serves liberal goals.
