IN the wake of the presidential election, as Democrats realized that Republicans will soon control all three branches of the federal government, progressives disinclined to secede from the Union rediscovered another exit strategy: states’ rights.More detailed, doctrine-wise, is Ilya Somin in WaPo, with "Federalism, the Constitution, and sanctuary cities," explaining Printz v. United States (the anti-commandeering doctrine) and NFIB v. Sebelius (the limit on using the spending power to coerce compliance).
Mayors in several so-called sanctuary cities, including Los Angeles, Oakland, Chicago and New York, immediately reaffirmed their commitment not to work with federal immigration officials in detaining and deporting illegal immigrants....
This is the main subject I wrote about when I wrote for law journals. See, e.g., "The Vigor of Anti-Commandeering Doctrine in Times of Terror." My experience was that liberals and lefties got annoyed at the suggestion that doctrine from conservative Justices could serve liberal causes.
ADDED: The post title is not intended to imply that Ilya Somin is himself a man of the left. And he now has a newer post: "Trump, federal power, and the left – why liberals should help make federalism great again."
