In Federalist No. 46, Madison says, respecting unconstitutional acts of the federal government:T
he People can refuse to cooperate with federal officers [7th para];
State officials can oppose the feds [7th para];State Legislatures can invent legislative devices to impede & obstruct the federal government [7th para];
States can cooperate in concerted plans of resistance [8th para];
States can easily defeat the federal government’s schemes of usurpation [10th para]; and as the last resort,
States must defend themselves from the federal government – that’s why the People are armed.
So Jefferson, Hamilton and Madison tell us: When the federal government asks or directs States to do things which aren’t on the list, the proper response is, “No!”
