"Sanctuary laws" are another example of Democrats wanting nullification. Last time it was about slavery and tariff policy.
Now, mind you, if we had nullification, "red" states could refuse to allow the Federal government to enforce all sorts of intrusive and oppressive regulations that the left has foisted on us. If we go that way, though, we might as well go back to the Articles of Confederation, since the Federal government would effectively become just a mutual defense pact and source of unified foreign policy.
