The reason the States won’t nullify laws and regulations enforced by the Federal Government is because the States are dependant on federal tax money to fund their infrastructure. They suck on the milk of stolen money, and are now totally addicted. They will not nullify unconstitutional laws without risking their own re-election when the spigot gets turned off (as we are seeing with “common core” education funds). I believe the only real hope if our nation is to survive as a constitutional republic, is to do away with the income tax and the central bank. Otherwise, we purchase our own demise with our own money.
