Generally speaking, the Tenth Amendment is viewed as an artifact of a regressive time that is only used to advance racism and impede progress. So 1990s! So when Jan Brewer signs an Arizona law requiring police to determine whether a person was in the country legally critics claim it will mean an explosion of racial profiling by the state, and the Obama administration does everything it can to stop it. Immigration law is a federal matter, as you all know.

And when the administration is unsatisfied with Texas and other states enforcing the same federal law, Obama unilaterally, and without any of the oversight from the democratic process he pretends to cherish, exempts undocumented immigrants brought to the country as children from the law. Now, immigration is a matter of Washington edict, not something for the states or, perhaps, even Congress, to worry about.

But San Francisco, well, it’s the purview of the city council to decide what happens—as long as those decisions comport with long-term liberal goals.
