All eyes are on Texas, with numerous states having indicated their support for the Lone Star State’s defiance of the federal government.

Constitutionally, Texas is on solid ground.

I’ve heard some people say this: since immigration per se is not mentioned in the Constitution (although naturalization is), then the relevant power rests with the states. Such people proceed to deploy this argument in defense of so-called “sanctuary cities.”
